duplicate in interface ByteBufHolder

refCnt

public int refCnt()

Description copied from interface: ReferenceCounted

Returns the reference count of this object. If 0, it means this object has been deallocated.

Description copied from interface: ReferenceCounted

Increases the reference count by the specified increment.

Specified by:

retain in interface ByteBufHolder

Specified by:

retain in interface ReferenceCounted

touch

public ByteBufHolder 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 via ResourceLeakDetector. This method is a shortcut to touch(null).

Specified by:

touch in interface ByteBufHolder

Specified by:

touch in interface ReferenceCounted

touch

public ByteBufHolder touch(Object hint)

Description copied from interface: ReferenceCounted

Specified by:

touch in interface ByteBufHolder

Specified by:

touch in interface ReferenceCounted

release

public boolean release()

Description copied from interface: ReferenceCounted

Decreases the reference count by 1 and deallocates this object if the reference count reaches at 0.

Specified by:

release in interface ReferenceCounted

Returns:

true if and only if the reference count became 0 and this object has been deallocated

release

public boolean release(int decrement)

Description copied from interface: ReferenceCounted

Decreases the reference count by the specified decrement and deallocates this object if the reference count reaches at 0.

Specified by:

release in interface ReferenceCounted

Returns:

true if and only if the reference count became 0 and this object has been deallocated
