CE-1180 Better built-in support for processes with dynamic flows - that is:
- in a backendStepOutput, you can set overrideLastStepName and call updateStepList - those values then flow through RunProcessAction to the runProcessOutput, then out through the javalin to the frontend.

|
||||
==== Custom Process Flow
|
||||
As referenced in the definition of the <<_QProcessMetaData_Properties,QProcessMetaData Properties>>, by default, a process
|
||||
will execute each of its steps in-order, as defined in the `stepList` property.
|
||||
However, a Backend Step can customize this flow #todo - write more clearly here...
|
||||
|
||||
There are generally 2 method to call (in a `BackendStep`) to do a dynamic flow:
|
||||
|
||||
* `RunBackendStepOutput.setOverrideLastStepName(String stepName)`
|
||||
** QQQ's `RunProcessAction` keeps track of which step it "last" ran, e.g., to tell it which one to run next.
|
||||
However, if a step sets the `OverrideLastStepName` property in its output object,
|
||||
then the step named in that property becomes the effective "last" step,
|
||||
thus determining which step comes next.
|
||||
|
||||
* `RunBackendStepOutput.updateStepList(List<String> stepNameList)`
|
||||
** Calling this method changes the process's runtime definition of steps to be executed.
|
||||
Thus allowing a completely custom flow.
|
||||
It should be noted, that the "last" step name (as tracked by QQQ within `RunProcessAction`)
|
||||
does need to be found in the new `stepNameList` - otherwise, the framework will not know where you were,
|
||||
for figuring out where to go next.
|
||||

||||

.Example of a defining process that can use a flexible flow:
|
||||
----
|
||||
// for a case like this, it would be recommended to define all step names in constants:
|
||||
public final static String STEP_START = "start";
|
||||
public final static String STEP_A = "a";
|
||||
public final static String STEP_B = "b";
|
||||
public final static String STEP_C = "c";
|
||||
public final static String STEP_1 = "1";
|
||||
public final static String STEP_2 = "2";
|
||||
public final static String STEP_3 = "3";
|
||||
public final static String STEP_END = "end";
|
||||
|
||||
// also, to define the possible flows (lists of steps) in constants as well:
|
||||
public final static List<String> LETTERS_STEP_LIST = List.of(
|
||||
STEP_START, STEP_A, STEP_B, STEP_C, STEP_END);
|
||||
|
||||
public final static List<String> NUMBERS_STEP_LIST = List.of(
|
||||
STEP_START, STEP_1, STEP_2, STEP_3, STEP_END);
|
||||
|
||||
// when we define the process's meta-data, we only give a "skeleton" stepList -
|
||||
// we must at least have our starting step, and we may want at least one frontend step
|
||||
// for the UI to show some placeholder(s):
|
||||
QProcessMetaData process = new QProcessMetaData()
|
||||
.withName(PROCESS_NAME)
|
||||
.withStepList(List.of(
|
||||
new QBackendStepMetaData().withName(STEP_START)
|
||||
.withCode(new QCodeReference(/*...*/)),
|
||||
new QFrontendStepMetaData()
|
||||
.withName(STEP_END)
|
||||
));
|
||||
|
||||
// the additional steps get added via `addOptionalStep`, which only puts them in
|
||||
// the process's stepMap, not its stepList!
|
||||
process.addOptionalStep(new QFrontendStepMetaData().withName(STEP_A));
|
||||
process.addOptionalStep(new QBackendStepMetaData().withName(STEP_B)
|
||||
.withCode(new QCodeReference(/*...*/)));
