A handler which may be registered with an Ehcache, to handle exceptions on Cache operations.
Handlers may be registered at configuration time in ehcache.xml, using a CacheExceptionHandlerFactory, or
set at runtime (a strategy).
If an exception handler is registered, the default behaviour of throwing the exception will not occur. The handler
method onException
will be called. Of course, if the handler decides to throw the exception, it will
propagate up through the call stack. If the handler does not, it won't.
Some common Exceptions thrown, and which therefore should be considered when implementing this class are listed below:
-
IllegalStateException if the cache is not
net.sf.ehcache.Status#STATUS_ALIVE
-
IllegalArgumentException if an attempt is made to put a null element into a cache
-
net.sf.ehcache.distribution.RemoteCacheException if an issue occurs in remote synchronous replication
