Method Summary

Modifier and Type	Method and Description
void	afterCreate(com.gemstone.gemfire.cache.EntryEvent event) This method performs the following tasks: 1)Increment the count of afterCreate in Validator 2)Verify that value received in the event is not null as Feeder always does create() on a key with a Long value.
void	afterDestroy(com.gemstone.gemfire.cache.EntryEvent event) This method performs the following tasks: If the old value is null, it implies that Feeder did a invalidate() in its previous operation on this key and hence no need to update the local latestValues map.
void	afterInvalidate(com.gemstone.gemfire.cache.EntryEvent event) This method performs the following tasks: 1)Increment the count of afterInvalidate in Validator
void	afterUpdate(com.gemstone.gemfire.cache.EntryEvent event) This method performs the following tasks: 1)Increment the count of afterUpdate in Validator 2)Verify that value received in the event is not null as Feeder always generates update on a key with a Long value one more than the previous one on this key.
