ReferenceCounted
.Modifier and Type | Method and Description |
---|---|
static int |
refCnt(Object msg)
Returns reference count of a
ReferenceCounted object. |
static boolean |
release(Object msg)
Try to call
ReferenceCounted.release() if the specified message implements ReferenceCounted . |
static boolean |
release(Object msg,
int decrement)
Try to call
ReferenceCounted.release(int) if the specified message implements ReferenceCounted . |
static <T> T |
releaseLater(T msg)
Deprecated.
this may introduce a lot of memory usage so it is generally preferable to manually release objects.

Unlike release(Object)
this method catches an exception raised by ReferenceCounted.release()
and logs it, rather than rethrowing it to the caller. It is usually recommended to use release(Object)
instead, unless you absolutely need to swallow an exception.public static void safeRelease(Object msg, int decrement)
