execute

public void execute(java.lang.Runnable work,
                    long timeout)

Description copied from interface: WorkQueue

Submits a work item for execution at some time in the future, waiting for up to a specified amount of time for the item to be accepted.

Specified by:

execute in interface WorkQueue

Parameters:

work - the workitem to submit for execution.

timeout - the maximum amount of time (in milliseconds) to wait for it to be accepted.
