prepare

public void prepare()

prepareTaskMethod

protected void prepareTaskMethod()

Called before executeTaskMethod(). The default implementation does nothing, and is provided only for the benefit of subclasses to override.

executeTaskMethod

protected boolean executeTaskMethod()

Invokes the actual pojo task method.

Called after prepareTaskMethod() by the thread that will be used to invoke the method. This thread may or may not be the same as the one in prepareTaskMethod. It will be different if the orchestrator decided to run this task in a separate thread in order to maximize parallelism.

This method can be overridden but this super method should be invoked from the overridden method to actually perform the call.

Returns:

boolean result of invoking task method

getClosure

public TaskMethodClosure getClosure()

Returns a closure for nested (non-root, i.e. tasks that have to wait for other tasks to finish) tasks. This implementation returns null indicating that the closure should be retrieved from IBascomConfig.getExecutionHook(Orchestrator, String).getClosure(). Subclasses can override to provide different behavior for non-root vs. root tasks, if desired. The difference with this method is that subclasses can know what the parent closure is, if that matters.

Specified by:

getClosure in interface ITaskClosureGenerator

Returns:

a closure ready for execution
