public interface Pool
Pools are used to track shared resource consumption. Each store participating in a pool creates an accessor which it uses to tell the pool about its consumption. A SizeOf engine is used to calculate the size of the objects added to the pool.
Method Summary | |
---|---|
PoolAccessor |
createPoolAccessor(PoolParticipant participant,
int maxDepth,
boolean abortWhenMaxDepthExceeded)
Return a PoolAccessor whose consumption is tracked by this pool, using a default SizeOf engine. |
PoolAccessor |
createPoolAccessor(PoolParticipant participant,
SizeOfEngine sizeOfEngine)
Return a PoolAccessor whose consumption is tracked by this pool, using a specific SizeOf engine. |
PoolEvictor |
getEvictor()
Return the pool evictor used by this pool. |
long |
getMaxSize()
Return the maximum size of the pool. |
Collection<PoolAccessor> |
getPoolAccessors()
Return the participants accessing this pool. |
long |
getSize()
Return the used size of the pool. |
void |
registerPoolAccessor(PoolAccessor accessor)
Register an accessor implementation with this pool. |
void |
removePoolAccessor(PoolAccessor accessor)
Remove the supplied accessor from this pool. |
void |
setMaxSize(long newSize)
Change the maximum size of the pool. |
