clear

public void clear()

Specified by:

close

public void close()

The shutdown takes place in two phases. First all caches are notified to cancel their scheduled timer jobs, after that the shutdown is done. Cancelling the timer jobs first is needed, because there may be cache stacking and a timer job of one cache may call an already closed cache.

Rationale exception handling: Exceptions on shutdown just could silently ignored, because a shutdown is done any way. Exceptions could be happened long before in a parallel task, shutdown is the last point where this could be propagated to the application. Silently ignoring is bad anyway, because this will cause that serious problems keep undetected. The exception and error handling within the cache tries everything that exceptions will be routed through as early and directly as possible.
