Package de.aristaflow.adept2.util.threading

Class CleanupRunnable

java.lang.Object

de.aristaflow.adept2.util.threading.CleanupRunnable

All Implemented Interfaces:

Runnable

public class CleanupRunnable
extends Object
implements Runnable

A cleanup runnable executes a runnable (or several ones) and afterwards a special cleanup runnable finally after the first runnable. Problems occurring in the cleanup runnable will be logged to the designated logger (and added as suppressed to problems of the runnable if appropriate). This way exceptions from the first runnable will not be swallowed.

CleanupRunnable

public CleanupRunnable(Runnable runnable,
                       Runnable cleanup,
                       Logger logger)

                       Runnable cleanup,
                       Logger logger)

Creates a new cleanup runnable executing the first runnable (and similar runnables concurrently) and the cleanup runnable finally right after the last of these runnables have terminated. Problems occurring in the cleanup runnable will be logged to the designated logger, RuntimeExceptions will be additionally added as suppressed to an exception of the first runnable if present.

Parameters:

runnable - The runnable executed normally.

sharingCount - The count for synchronising similar runnables so that cleanup will not run before all runnables have terminated.
