touch
public AdaptivePoolingAllocator.Chunk touch(java.lang.Object hint)
Description copied from interface:ReferenceCounted
Records the current access location of this object with an additional arbitrary information for debugging purposes. If this object is determined to be leaked, the information recorded by this operation will be provided to you viaResourceLeakDetector
.- Specified by:
touch
in interfaceReferenceCounted
-
refCnt
public int refCnt()
Description copied from interface:ReferenceCounted
Returns the reference count of this object. If0
, it means this object has been deallocated.- Specified by:
refCnt
in interfaceReferenceCounted
-
retain
public AdaptivePoolingAllocator.Chunk retain()
Description copied from interface:ReferenceCounted
Increases the reference count by1
.- Specified by:
retain
in interfaceReferenceCounted
-
retain
public AdaptivePoolingAllocator.Chunk retain(int increment)
Description copied from interface:ReferenceCounted
Increases the reference count by the specifiedincrement
.- Specified by:
retain
in interfaceReferenceCounted
-
touch
public AdaptivePoolingAllocator.Chunk touch()
Description copied from interface:ReferenceCounted
Records the current access location of this object for debugging purposes. If this object is determined to be leaked, the information recorded by this operation will be provided to you viaResourceLeakDetector
. This method is a shortcut totouch(null)
.- Specified by:
touch
in interfaceReferenceCounted
-
release
public boolean release()
Description copied from interface:ReferenceCounted
Decreases the reference count by1
and deallocates this object if the reference count reaches at0
.- Specified by:
release
in interfaceReferenceCounted
- Returns:
true
if and only if the reference count became0
and this object has been deallocated
-
