Version:

2.1.2

This template encapsulates the common behavior of threaded executors. It provides a means to select a locking mechananism & task queue class via template parameters.

Any Executor can be extended and can override the createWorker() function to alter how the Work threads behave.

Member Function Documentation

virtual bool available (    )  throw (Synchronization_Exception) [inline, virtual]

Block until this executor has become available to run new tasks. This does not guarantee that another thread won't have submitted a task before some action is taken in response to this. However, it is useful as a general heuristic Returns: boolean Exceptions: InterruptedException  Reimplemented in PoolExecutor.

virtual void cancel (    )  throw (Synchronization_Exception) [inline, virtual]

Stop the execution of additional tasks by this executor. After this method has be invoked then the Executor will completed when the last task it was previously assigned is completed. Exceptions: InterruptedException  Postcondition: the executor no longer accepts new tasks. At this point the executor has a limited lifetime and is safe to join See also: Executor::cancel() Implements Executor.

virtual Thread* createWorker (    )  [protected, pure virtual]

Create a new worker for the Executor, allows extedned classes to more easily special Worker objects w/o reimplementing the entire executor. Implemented in PoolExecutor.

virtual bool isCanceled (    )  throw (Synchronization_Exception) [inline, virtual]

Check the cancelation status of this Executor Returns: bool - Executor canceled See also: Cancelable::isCanceled() Implements Cancelable.
