public TaskExecutor(String sTaskId,
                    boolean fRecovered)

Constructs a ClusteredRegistration.TaskExecutor.

Parameters:

sTaskId - the identity of the Task to execute

fRecovered - if the Task was previously assigned to a different Executor

Method Detail

setResult

public void setResult(Result result)

Set the result processing result.

Parameters:

result - the result to report

setResult

public void setResult(Result result,
                      boolean fComplete)

Set the result processing result.

Parameters:

result - the result to report

run

public void run()

Specified by:

run in interface Runnable

setResult

public void setResult(Object result)

Description copied from interface: Task.Context

Sets the intermediate result a Task has produced while being executed by an Executor as part of an Task.Orchestration.

The provided result may be later collected by an TaskExecutorService according to the configured Task.Collector and then published to registered Task.Subscribers.

Specified by:

setResult in interface Task.Context

Parameters:

result - the result

isDone

public boolean isDone()

Description copied from interface: Task.Context

Determines if a Task completed according to the TaskExecutorService.

Completion may be due to normal termination, an exception or cancellation. In all of these cases, this method will return true.
