+== QueryAction
+include::../variables.adoc[]
+
+The `*QueryAction*` is the basic action that is used to get records from a {link-table}.
+In SQL/RDBMS terms, it is analogous to a `SELECT` statement, where 0 or more records may be found and returned.
+
+=== Examples
+==== Basic Form
+[source,java]
+----
+QueryInput input = new QueryInput(qInstance);
+input.setSession(session);
+input.setTableName("orders");
+input.setFilter(new QQueryFilter()
+   .withCriteria(new QFilterCriteria("total", GREATER_THAN, new BigDecimal("3.50")))
+   .withOrderBy(new QFilterOrderBy("orderDate", false))
+);
+QueryOutput output = new QueryAction.execute(input);
+List<QRecord> records = output.getRecords();
+----
+
+=== QueryInput
+* `table` - *String, Required* - Name of the table being queried against.
+* `filter` - *QQueryFilter object* - Specification for what records should be returned, based on *QFilterCriteria* objects, and how they should be sorted, based on *QFilterOrderBy* objects.
+* `skip` - *Integer* - Optional number of records to be skipped at the beginning of the result set.
+e.g., for implementing pagination.
+* `limit` - *Integer* - Optional maximum number of records to be returned by the query.
+* `transaction` - *QBackendTransaction object* - Optional transaction object.
+** Behavior for this object is backend-dependant.
+In an RDBMS backend, this object is generally needed if you want your query to see data that may have been modified within the same transaction.
+* `recordPipe` - *RecordPipe object* - Optional object that records are placed into, for asynchronous processing.
+** If a *recordPipe* is used, then records cannot be retrieved from the *QueryOutput*.
+Rather, such records must be read from the pipe's `consumeAvailableRecords()` method.
+** A *recordPipe* should only be used when a *QueryAction* is running in a separate Thread from the record's consumer.
+* `shouldTranslatePossibleValues` - *boolean, default: false* - Controls whether any fields in the table with a *possibleValueSource* assigned to them should have those possible values looked up
+(e.g., to provide text translations in the generated records' `displayValues` map).
+** For example, if running a query to present results to a user, this would generally need to be *true*.
+But if running a query to provide data as part of a process, then this can generally be left as *false*.
+* `shouldGenerateDisplayValues` - *boolean, default: false* - Controls whether if field level *displayFormats* should be used to populate the generated records' `displayValues` map.
+** For example, if running a query to present results to a user, this would generally need to be *true*.
+But if running a query to provide data as part of a process, then this can generally be left as *false*.
+* `queryJoins` - *List of QueryJoin objects* - Optional list of tables to be joined with the main *table* specified in the *QueryInput*.
+See QueryJoin below for further details.
+
+==== QQueryFilter
+A key component of *QueryInput*, a *QQueryFilter* defines both what records should be included in a query's results (e.g., an SQL `WHERE`), as well as how those results should be sorted (SQL `ORDER BY`).
+
+* `criteria` - *List of QFilterCriteria* - Individual conditions or clauses to filter records.
+They are combined using the *booleanOperator* specified in the *QQueryFilter*.  See below for further details.
+* `orderBys` - *List of QFilterOrderBy* - List of fields (and directions) to control the sorting of query results.
+In general, multiple *orderBys* can be given (depending on backend implementations).
+* `booleanOperator` - *Enum of AND, OR, default: AND* - Specifies the logical joining operator used among individual criteria.
+* `subFilters` - *List of QQueryFilter* - To build arbitrarily complex queries, with nested boolean logic, 0 or more *subFilters* may be provided.
+** Each *subFilter* can include its own additional *subFilters*.
+** Each *subFilter* can specify a different *booleanOperator*.
+** For example, consider the following *QQueryFilter*, that uses two *subFilters*, and a mix of *booleanOperators*
+
+[source,java]
+----
+ queryInput.setFilter(new QQueryFilter()
+    .withBooleanOperator(OR)
+    .withSubFilters(List.of(
+       new QQueryFilter().withBooleanOperator(AND)
+          .withCriteria(new QFilterCriteria("firstName", EQUALS, "James"))
+          .withCriteria(new QFilterCriteria("lastName", EQUALS, "Maes")),
+       new QQueryFilter().withBooleanOperator(AND)
+          .withCriteria(new QFilterCriteria("firstName", EQUALS, "Darin"))
+          .withCriteria(new QFilterCriteria("lastName", EQUALS, "Kelkhoff"))
+    )));
+
+// which would generate the following WHERE clause in an RDBMS backend:
+   WHERE (first_name='James' AND last_name='Maes') OR (first_name='Darin' AND last_name='Kelkhoff')
+----
+
+===== QFilterCriteria
+* `fieldName` - *String, required* - Reference to a field on the table being queried.
+** Or, in the case of a query with *queryJoins*, a qualified name of a field from a join-table (where the qualifier would be the joined table's name or alias, followed by a dot)
+*** For example:  `orderLine.sku` or `orderBillToCustomer.firstName`
+* `operator` - *Enum of QCriteriaOperator, required* - Comparison operation to be applied to the field specified as *fieldName* and the *values* or *otherFieldName*.
+** e.g., `EQUALS`, `NOT_IN`, `GREATER_THAN`, `BETWEEN`, `IS_BLANK`, etc.
+* `values` - *List of values, conditional* - Provides the value(s) that the field is compared against.
+The number of values (0, 1, 2, or more) be driven based on the *operator* being used.
+If an *otherFieldName* is given, and the *operator* expects 1 value, then *values* is ignored, and *otherFieldName* is used.
+* `otherFieldName` - *String, conditional* - Specifies that the *fieldName* should be compared against another field in the records, rather than the values in the *values* property.
+Only used for *operators* that expect 1 value (e.g., `EQUALS` or `LESS_THAN_OR_EQUALS` - not `IS_NOT_BLANK` or `IN`).
+
+QFilterCriteria definition examples:
+[source,java]
+----
+// one-liners, via constructors that take (List<Serializable> values) or (Serializable... values) in 3rd position
+new QFilterCriteria("id", IN, List.of(1, 2, 3))
+new QFilterCriteria("name", IS_BLANK)
+new QFilterCriteria("orderNo", IN, orderNoList)
+new QFilterCriteria("state", EQUALS, "MO");
+
+// long-form, with fluent setters
+new QFilterCriteria()
+   .withFieldName("quantity")
+   .withOpeartor(QCriteriaOperator.GREATER_THAN)
+   .withValues(List.of(47));
+
+// to use otherFieldName, long-form must be used
+new QFilterCriteria()
+   .withFieldName("firstName")
+   .withOpeartor(QCriteriaOperator.EQUALS)
+   .withOtherFieldName("lastName");
+
+// using otherFieldName to build a criterion that looks at two fields from join tables
+new QFilterCriteria()
+   .withFieldName("billToCustomer.lastName")
+   .withOpeartor(QCriteriaOperator.NOT_EQUALS)
+   .withOtherFieldName("shipToCustomer.lastName");
+
+----
+
+===== QFilterOrderBy
+* `fieldName` - *String, required* - Reference to a field on the table being queried.
+** Or, in the case of a query with *queryJoins*, a qualified name of a field from a join-table (where the qualifier would be the joined table's name or alias, followed by a dot)
+* `isAscending` - *boolean, default: true* - Specify if the sort is ascending or descending.
+
+QFilterCriteria definition examples:
+
+[source,java]
+----
+// short-form, via constructors
+new QFilterOrderBy("id") // isAscending defaults to true.
+new QFilterOrderBy("name", false)
+
+// long-form, with fluent setters
+new QFilterOrderBy()
+   .withFieldName("birthDate")
+   .withIsAscending(true);
+----
+
+==== QueryJoin
+* `joinTable` - *String, required* - Name of the table that is being joined in to the existing query.
+** Will be inferred from *joinMetaData*, if *joinTable* is not set when *joinMetaData* gets set.
+* `baseTableOrAlias` - *String, required* - Name of a table (or an alias) already defined in the query, to which the *joinTable* will be joined.
+** Will be inferred from *joinMetaData*, if *baseTableOrAlias* is not set when *joinMetaData* gets set (which will only use the leftTableName from the joinMetaData - never an alias).
+* `joinMetaData` - *QJoinMetaData object* - Optional specification of a {link-join} in the current QInstance.
+If not set, will be looked up at runtime based on *baseTableOrAlias* and *joinTable*.
+** If set before *baseTableOrAlias* and *joinTable*, then they will be set based on the *leftTable* and *rightTable* in this object.
+* `alias` - *String* - Optional (unless multiple instances of the same table are being joined together, when it becomes required).
+Behavior based on SQL `FROM` clause aliases.
+If given, must be used as the part before the dot in field name specifications throughout the rest of the query input.
+* `select` - *boolean, default: false* - Specify whether fields from the *rightTable* should be selected by the query.
+If *true*, then the `QRecord` objects returned by this query will have values with corresponding to the (table-or-alias `.` field-name) form.
+* `type` - *Enum of INNER, LEFT, RIGHT, FULL, default: INNER* - specifies the SQL-style type of join being performed.
+
+QueryJoin definition examples:
+
+[source,java]
+----
+// selecting from an "orderLine" table - then join to its corresponding "order" table
+queryInput.withTableName("orderLine");
+queryInput.withQueryJoin(new QueryJoin("order").withSelect(true));
+...
+queryOutput.getRecords().get(0).getValueBigDecimal("order.grandTotal");
+
+// given an "order" table with 2 foreign keys to a customer table (billToCustomerId and shipToCustomerId)
+// Note, we must supply the JoinMetaData to the QueryJoin, to drive what fields to join on in each case.
+queryInput.withTableName("order");
+queryInput.withQueryJoins(List.of(
+   new QueryJoin(instance.getJoin("orderJoinShipToCustomer")
+       .withAlias("shipToCustomer")
+       .withSelect(true)),
+   new QueryJoin(instance.getJoin("orderJoinBillToCustomer")
+       .withAlias("billToCustomer")
+       .withSelect(true))));
+...
+record.getValueString("billToCustomer.firstName")
+   + " placed an order for "
+   + record.getValueString("shipToCustomer.firstName")
+
+----
+
+=== QueryOutput
+* `records` - *List of QRecord* - List of 0 or more records that match the query filter.
+** _Note:  If a *recordPipe* was supplied to the QueryInput, then calling `queryOutput.getRecords()` will result in an `IllegalStateException` being thrown - as the records were placed into the pipe as they were fetched, and cannot all be accessed as a single list._

+== QQQ Reports
+include::../variables.adoc[]
+
+QQQ can generate reports based on {link-tables} defined within a QQQ Instance.
+Users can run reports, providing input values.
+Alternatively, application code can run reports as needed, supplying input values.
+
+=== QReportMetaData
+Reports are defined in a QQQ Instance with a `*QReportMetaData*` object.
+Reports are defined in terms of their sources of data (`QReportDataSource`), and their view(s) of that data (`QReportView`).
+
+*QReportMetaData Properties:*
+
+* `name` - *String, Required* - Unique name for the report within the QQQ Instance.
+* `label` - *String* - User-facing label for the report, presented in User Interfaces.
+Inferred from `name` if not set.
+* `processName` - *String* - Name of a {link-process} used to run the report in a User Interface.
+* `inputFields` - *List of {link-field}* - Optional list of fields used as input to the report.
+** The values in these fields can be used via the syntax `${input.NAME}`, where `NAME` is the `name` attribute of the `inputField`.
+** For example:
+
+[source,java]
+----
+// given this inputField:
+new QFieldMetaData("storeId", QFieldType.INTEGER)
+
+// its run-time value can be accessed, e.g., in a query filter under a data source:
+new QFilterCriteria("storeId", QCriteriaOperator.EQUALS, List.of("${input.storeId}"))
+
+// or in a report view's title or field formulas:
+.withTitleFields(List.of("${input.storeId}"))
+new QReportField().withName("storeId").withFormula("${input.storeId}")
+----
+
+* `dataSources` - *List of QReportDataSource, Required* - Definitions of the sources of data for the report.
+At least one is required.
+
+==== QReportDataSource
+Data sources for QQQ Reports can either reference {link-tables} within the QQQ Instance, or they can provide custom code in the form of a `CodeReference` to a  `Supplier`, for use cases such as a static data tab in an Excel report.
+
+*QReportDataSource Properties:*
+
+* `name` - *String, Required* - Unique name for the data source within its containing Report.
+* `sourceTable` - *String, Conditional* - Reference to a {link-table} in the QQQ Instance, which the data source queries data from.
+* `queryFilter` - *QQueryFilter* - If a `sourceTable` is defined, then the filter specified here is used to filter and sort the records queried from that table when generating the report.
+* `staticDataSupplier` - *QCodeReference, Conditional* - Reference to custom code which can be used to supply the data for the data source, as an alternative to querying a `sourceTable`.
+** Must be a `JAVA` code type
+** Must be a `REPORT_STATIC_DATA_SUPPLIER` code usage.
+** The referenced class must implement the interface: `Supplier<List<List<Serializable>>>`.
+
+==== QReportView
+Report Views control how the source data for a report is organized and presented to the user in the output report file.
+If a DataSource describes the rows for a report (e.g., what table provides what records), then a View may be thought of as describing the columns in the report.
+A single report can have multiple views, specifically, for the use-case where an Excel file is being generated, in which case each View creates a tab or sheet within the `xlsx` file.
+
+*QReportView Properties:*
+
+* `name` - *String, Required* - Unique name for the view within its containing Report.
+* `label` - *String* - Used as a sheet (tab) label in Excel formatted reports.
+* `type` - *enum of TABLE, SUMMARY, PIVOT. Required* - Defines the type of view being defined.
+** *TABLE* views are a simple listing of the records from the data source.
+** *SUMMARY* views are essentially pre-computed Pivot Tables.
+That is to say, the aggregation done by a Pivot Table in a spreadsheet file is done by QQQ while generating the report.
+In this way, a non-spreadsheet report (e.g., PDF or CSV) can have summarized data, as though it were a Pivot Table in a live spreadsheet.
+** *PIVOT* views produce actual Pivot Tables, and are only supported in Excel files _(and are not supported at the time of this writing)_.
+* `dataSourceName` - *String, Required* - Reference to a DataSource within the report, that is used to provide the rows for the view.
+* `varianceDataSourceName` - *String* - Optional reference to a second DataSource within the report, that is used in `*SUMMARY*` type views for computing variances.
+** For example, given a Data Source with a filter that selects all sales records for a given year, a Variance Data Source may have a filter that selects the previous year, for doing comparissons.
+* `pivotFields` - *List of String, Conditional* - For *SUMMARY* or *PIVOT* type views, specify the field(s) used as pivot rows.
+** For example, in a summary view of orders, you may "pivot" on the *customerId* field, to produce one row per-customer, with aggregate data for that customer.
+* `titleFormat` - *String* - Java Format String, used with `titleFields` (if given), to produce a title row, e.g., first row in the view (before any rows from the data source).
+* `titleFields` - *List of String, Conditional* - Used with `titleFormat`, to provide values for any format specifiers in the format string.
+Syntax to reference a field (e.g., from a report input field) is: `${input.NAME}`, where `NAME` is the `name` attribute of the inputField.
+** Example of using `titleFormat` and `titleFields`:
+
+[source,java]
+----
+// given these inputFields:
+new QFieldMetaData("startDate", QFieldType.DATE)
+new QFieldMetaData("endDate", QFieldType.DATE)
+
+// a view can have a title row like this:
+.withTitleFormat("Weekly Sales Report - %s - %s")
+.withTitleFields(List.of("${input.startDate}", "${input.endDate}"))
+----
+
+* `includeHeaderRow` - *boolean, default true* - Indication that first row of the view should be the column labels.
+** If true, then header row is put in the view.
+** If false, then no header row is put in the view.
+* `includeTotalRow` - *boolean, default false* - Indication that a totals row should be added to the view.
+All numeric columns are summed to produce values in the totals row.
+** If true, then totals row is put in the view.
+** If false, then no totals row is put in the view.
+* `includePivotSubTotals` - *boolean, default false* - For a *SUMMARY* or *PIVOT* type view, if there are more than 1 *pivotFields* being used, this field is an indication that each higher-level pivot should include sub-totals.
+** #TODO - provide example#
+* `columns` - *List of QReportField, required* - Definition of the columns to appear in the view.  See section on QReportField for details.
+* `orderByFields` - *List of QFilterOrderBy, optional* - For a *SUMMARY* or *PIVOT* type view, how to sort the rows.
+* `recordTransformStep` - *QCodeReference, subclass of `AbstractTransformStep`* - Custom code reference that can be used to transform records after they are queried from the data source, and before they are placed into the view.
+Can be used to transform or customize values, or to look up additional values to add to the report.
+** #TODO - provide example#
+* `viewCustomizer` - *QCodeReference, implementation of interface `Function<QReportView, QReportView>`* - Custom code reference that can be used to customize the report view, at runtime.
+Can be used, for example, to dynamically define the report's *columns*.
+** #TODO - provide example#
+
+===== QReportField
+Report Fields define the fields (AKA columns) of data that appear in a report view.
+These fields can either be direct references to fields from the report's data sources, or values computed using formula defined in the QReportField.
+
+*QReportField Properties:*
+
+* `name` - *String, required* - Unique identifier for the field within its ReportView.
+In general, will be a reference to a field from the ReportView's DataSource *unless a *formula* is given (for *SUMMARY* type views), the field is marked as *isVirtual*, or the field is marked as *showPossibleValueLabel*).
+* `label` - *String* - Optional text label to identify the field, for example, in a header row.
+If not given, may be derived from field, where possible.
+* `type` - *QFieldType*
+* `formula` - *String, conditional* - Required for *SUMMARY* type views.
+Defines the formula to be used for computing the value in this field.
+** For example:
+
+[source,java]
+----
+.withName("reportEndDate").withFormula("${input.endDate}")
+
+.withName("count").withFormula("${pivot.count.id}")
+
+.withName("percentOfTotal").withFormula("=DIVIDE(${pivot.count.id},${total.count.id})")
+
+.withName("sumCost").withFormula("${pivot.sum.cost}")
+
+.withName("sumCharge").withFormula("${pivot.sum.charge}")
+
+.withName("profit").withFormula("=MINUS(${pivot.sum.charge},${pivot.sum.cost})")
+
+.withName("totalCost").withFormula("=DIVIDE_SCALE(${pivot.sum.cost},${pivot.count.id},2)")
+
+.withName("revenuePer").withFormula("=DIVIDE_SCALE(${pivot.sum.charge},${pivot.count.id},2)")
+
+.withName("marginPer").withFormula("=MINUS(DIVIDE_SCALE(${pivot.sum.charge},${pivot.count.id},2),DIVIDE_SCALE(${pivot.sum.cost},${pivot.count.id},2))")
+
+.withName("thisWeekMargin").withFormula("=SCALE(DIVIDE(${thisRow.profit},${pivot.sum.charge}),2)")
+
+.withName("previousWeekProfit").withFormula("=MINUS(${variancePivot.sum.charge},${variancePivot.sum.cost})")
+
+.withName("previousWeekMargin").withFormula("=SCALE(DIVIDE(${thisRow.previousWeekProfit},${variancePivot.sum.charge}),2)")
+
+.withName("marginThisVsPrevious").withFormula("=SCALE(MINUS(${thisRow.margin},${thisRow.marginPrevious}),3)")
+
+.withName("exception").withFormula("""
+   =IF(LT(${thisRow.margin},0),Negative Margin,IF(LT(${thisRow.marginThisVsPrevious},0),Margin Decreased,""))""")
+----
+
+* `displayFormat` *String*
+* `isVirtual` *Boolean, default false* - (needs reviewed - may only be required for report views using a data source with a *staticDataSupplier*)
+* `showPossibleValueLabel` *Boolean, default false* - To show a translated value for a Possible Value field (e.g., a name or other value meaningful to a user, instead of a foreign key).
+* `sourceFieldName` *String* - Used for the scenario where a possibleValue field is included in a report both as the foreign key (raw, id value), and the translated "label" value.
+In that case, the field marked with *showPossibleValueLabel* = true should be given a different name, and should use *sourceFieldName* to indicate the field that has the id value.
+** For example:
+
+[source,java]
+----
+// this field would have the "raw" warehouseId values
+// e.g., integers - foreign keys to a warehouse table.  Generally useful for machines to know.
+new QReportField("warehouseId")
+   .withLabel("Warehouse Id"),
+
+// this field would have the translated values from the warehouse PossibleValueSource
+// for example, maybe the name field from the warehouse table.  A string, useful for humans to read.
+new QReportField("warehouseName")
+   .withSourceFieldName("warehouseId")
+   .withShowPossibleValueLabel(true)
+   .withLabel("Warehouse Name"),

+== QQQ Tables
+include::../variables.adoc[]
+
+The core type of object in a QQQ Instance is the Table.
+In the most common use-case, a QQQ Table may be the in-app representation of a Database table.
+That is, it is a collection of records (or rows) of data, each of which has a set of fields (or columns).
+
+QQQ also allows other types of data sources ({link-backends}) to be used as tables, such as File systems, API's, Java enums or objects, etc.
+All of these backend types present the same interfaces (both user-interfaces, and application programming interfaces), regardless of their backend type.
+
+=== QTableMetaData
+Tables are defined in a QQQ Instance in a `*QTableMetaData*` object.
+All tables must reference a {link-backend}, a list of fields that define the shape of records in the table, and additional data to describe how to work with the table within its backend.
+
+*QTableMetaData Properties:*
+
+* `name` - *String, Required* - Unique name for the table within the QQQ Instance.
+* `label` - *String* - User-facing label for the table, presented in User Interfaces.
+Inferred from `name` if not set.
+* `backendName` - *String, Required* - Name of a {link-backend} in which this table's data is managed.
+* `fields` - *Map of String → {link-field}, Required* - The columns of data that make up all records in this table.
+* `primaryKeyField` - *String, Conditional* - Name of a {link-field} that serves as the primary key (e.g., unique identifier) for records in this table.
+* `uniqueKeys` - *List of UniqueKey* - Definition of additional unique constraints (from an RDBMS point of view) from the table.
+e.g., sets of columns which must have unique values for each record in the table.
+* `backendDetails` - *QTableBackendDetails or subclass* - Additional data to configure the table within its {link-backend}.
+* `automationDetails` - *QTableAutomationDetails* - Configuration of automated jobs that run against records in the table, e.g., upon insert or update.
+* `customizers` - *Map of String → QCodeReference* - References to custom code that are injected into standard table actions, that allow applications to customize certain parts of how the table works.
+* `parentAppName` - *String* - Name of a {link-app} that this table exists within.
+* `icon` - *QIcon* - Icon associated with this table in certain user interfaces.
+* `recordLabelFormat` - *String* - Java Format String, used with `recordLabelFields` to produce a label shown for records from the table.
+* `recordLabelFields` - *List of String, Conditional* - Used with `recordLabelFormat` to provide values for any format specifiers in the format string.
+These strings must be field names within the table.
+** Example of using `recordLabelFormat` and `recordLabelFields`:
+
+[source,java]
+----
+// given these fields in the table:
+new QFieldMetaData("name", QFieldType.STRING)
+new QFieldMetaData("birthDate", QFieldType.DATE)
+
+// We can produce a record label such as "Darin Kelkhoff (1980-05-31)" via:
+.withRecordLabelFormat("%s (%s)")
+.withRecordLabelFields(List.of("name", "birthDate"))
+----
+* `sections` - *List of QFieldSection* - Mechanism to organize fields within user interfaces, into logical sections.
+If any sections are present in the table meta data, then all fields in the table must be listed in exactly 1 section.
+If no sections are defined, then instance enrichment will define default sections.
+* `associatedScripts` - *List of AssociatedScript* - Definition of user-defined scripts that can be associated with records within the table.
+* `enabledCapabilities` and `disabledCapabilities` - *Set of Capability enum values* - Overrides from the backend level, for capabilities that this table does or does not possess.

+<p>The core type of object in a QQQ Instance is the Table.
+In the most common use-case, a QQQ Table may be the in-app representation of a Database table.
+That is, it is a collection of records (or rows) of data, each of which has a set of fields (or columns).</p>
+</div>
+<div class="paragraph">
+<p>QQQ also allows other types of data sources (<a href="Backends{relfilesuffix}">QQQ Backends</a>) to be used as tables, such as File systems, API&#8217;s, Java enums or objects, etc.
+All of these backend types present the same interfaces (both user-interfaces, and application programming interfaces), regardless of their backend type.</p>

+<h3 id="_qtablemetadata">QTableMetaData</h3>
+<div class="paragraph">
+<p>Tables are defined in a QQQ Instance in a <code><strong>QTableMetaData</strong></code> object.

+ ** custom actions before an update takes place.
+ **
+ ** It's important for implementations to be aware of the isPreview field, which
+ ** is set to true when the code is running to give users advice, e.g., on a review
+ ** screen - vs. being false when the action is ACTUALLY happening.  So, if you're doing
+ ** things like storing data, you don't want to do that if isPreview is true!!
+ **
+ ** General implementation would be, to iterate over the records (the inputs to
+ ** the update action), and look at their values:
+ ** - possibly adding Errors (`addError`) or Warnings (`addWarning`) to the records
+ ** - possibly manipulating values (`setValue`)
+ ** - possibly throwing an exception - if you really don't want the update operation to continue.
+ ** - doing "whatever else" you may want to do.
+ ** - returning the list of records (can be the input list) that you want to go on to the backend implementation class.
+ **
+ ** Note that the full updateInput is available as a field in this class, and the
+ ** "old records" (e.g., with values freshly fetched from the backend) will be
+ ** available (if the backend supports it) - both as a list (`getOldRecordList`)
+ ** and as a memoized (by this class) map of primaryKey to record (`getOldRecordMap`).
