Class SynchronousSimpleTarget

java.lang.Object

org.pvalsecc.concurrent.SynchronousTarget

org.pvalsecc.concurrent.SynchronousSimpleTarget

Direct Known Subclasses:

BlockingSimpleTarget

public class SynchronousSimpleTarget
extends SynchronousTarget

Used to do something (callback) when every sub-task is done.

The target number of jobs doesn't have to be known in advance, but has to be specified only once with setTarget.

When every task kinds are completed, the completedCallback Runnable is called either from addJobDone() or from setTarget().

This is not really a barrier as defined in the list of synchronization methods...
