Method Summary

Modifier and Type	Method	Description
protected abstract void	deallocate()	Called once refCnt() is equals 0.

AbstractReferenceCountedByteBuf

protected AbstractReferenceCountedByteBuf(int maxCapacity)

Method Detail

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.

setRefCnt

protected final void setRefCnt(int refCnt)

An unsafe operation intended for use by a subclass that sets the reference count of the buffer directly

resetRefCnt

protected final void resetRefCnt()

An unsafe operation intended for use by a subclass that resets the reference count of the buffer to 1

retain

public ByteBuf retain()

Description copied from interface: ReferenceCounted

Increases the reference count by 1.

Specified by:

retain in interface ReferenceCounted

Specified by:

retain in class ByteBuf

retain

public ByteBuf retain(int increment)

Description copied from interface: ReferenceCounted

Increases the reference count by the specified increment.

Specified by:

retain in interface ReferenceCounted

Specified by:

retain in class ByteBuf

touch

public ByteBuf 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 ReferenceCounted

Specified by:

touch in class ByteBuf

touch

public ByteBuf 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 via ResourceLeakDetector.

Specified by:

touch in interface ReferenceCounted

Specified by:

touch in class ByteBuf

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.

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.

Returns:

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

deallocate

protected abstract void deallocate()

Called once refCnt() is equals 0.
