int	getPurgeTarget() gets the purge target - i.e. the desired number of items remaining in the cache after a purge operation.
int	getUrgentCapacityTrigger() gets the urgent trigger cache level - when the cache reaches this level of capacity, an "urgent" purge request will be posted.
void	setCapacity(int capacity) Sets the nominal capacity of the cache
void	setEmergencyCapacityTrigger(int emergencyCapacityTrigger) Sets the emergency trigger cache level - when the cache reaches this level of capacity, any cache.put() oepration will immediately perform a purge operation.
void	setNormalCapacityTrigger(int normalCapacityTrigger) Sets the normal trigger cache level - when the cache reaches this level of capacity, an "normal" purge request will be posted.
void	setPurgeTarget(int purgeTarget) Sets the purge target - i.e. the desired number of items remaining in the cache after a purge operation.
