Method Detail

execute

boolean execute(ITask task)
                throws BatchException

Execute the given task, waiting for free space in blocking queue if necessary

Parameters:

task - the task to execute

Returns:

true is the task has been added to the execution queue, false otherwise (the user can shutdown this service through JMX)

Throws:

BatchException

isRunning

boolean isRunning()

Indicate the running state of the executor (the user can shutdown this service through JMX). If false, then no more task must be execute.

Returns:

true is the service is running, false otherwise

getTaskCount

long getTaskCount()

Returns the approximate total number of tasks that have been scheduled for execution. Because the states of tasks and threads may change dynamically during computation, the returned value is only an approximation, but one that does not ever decrease across successive calls.

Returns:

the number of tasks
