| Modifier and Type | Method and Description |
|---|---|
CompletableFuture<R> |
apply()
Creates a CompletableFuture around the lambda expression.
|
Object |
before(TaskRun taskRun)
Called before
TaskRunner.executeTaskMethod(TaskRun, Thread, Object), but in the parent thread. |
protected <RV> com.ebay.bascomtask.core.BascomTaskFuture<RV> |
ensureWrapped(CompletableFuture<RV> cf,
boolean registerAsDependentInput)
Ensures the provided CF is or is wrapped by a BT-controlled CF, and registered as an input argument.
|
Object |
executeTaskMethod(TaskRun taskRun,
Thread parentThread,
Object fromBefore)
Task invocation -- an implementation should invoke
TaskRun.run()
to complete the invocation (unless there is some reason to prevent it, but then the implementation
must take responsibility to ensure the all CompletableFuture return values are completed). |
void |
formatActualSignature(StringBuilder sb) |
long |
getCompletedAt()
Returns the time at which this task method was completed, which for CompletableFutures is the time
at which it had a value assigned.
|
long |
getEndedAt()
Returns the time at which this task method was ended.
|
String |
getName()
Returns the task name, e.g.
|
long |
getStartedAt()
Returns the time at which this task method was started.
|
TaskInterface<?> |
getTask()
Returns the user task pojo if there is one.

void |
onComplete(TaskRun taskRun,
Object fromBefore,
boolean doneOnExit)
Called once any CompletableFuture return result completes, which may be before the call to
TaskRun.run() or after if a method returns an incomplete CompletableFuture.

If there is no immediate spawning then it will be the same thread. The returned object will
simply be passed to executeTaskMethod and is otherwise not read or modified by the framework.before in interface TaskRunnertaskRun - that will also be passed to executeTaskMethodpublic Object executeTaskMethod(TaskRun taskRun, Thread parentThread, Object fromBefore)
TaskRunnerTaskRun.run()
to complete the invocation (unless there is some reason to prevent it, but then the implementation
must take responsibility to ensure the all CompletableFuture return values are completed). A typical
subclass implementation would be to simply surround the call, e.g.:
public Object executeTaskMethod(TaskRun taskRun, Thread parentThread, Object fromBefore) {
LOG.info("STARTED " + taskRun.getTaskPlusMethodName());
try {
taskRun.run()
} finally {
LOG.info("ENDED " + taskRun.getTaskPlusMethodName());
}
}

TaskRunnerThe provided doneOnExit parameter indicates whether a CompletableFuture return value had isDone()==true when the method completed. This should not be taken as very close but not exactly precise, since there are very small time intervals involved in the steps behind making that determination.
