| Modifier and Type | Method and Description |
|---|---|
protected abstract void |
deallocate()
Called once
refCnt() is equals 0. |
int |
refCnt()
Returns the reference count of this object.
|
boolean |
release()
Decreases the reference count by
1 and deallocates this object if the reference count reaches at
0. |
boolean |
release(int decrement)
Decreases the reference count by the specified
decrement and deallocates this object if the reference
count reaches at 0. |
ByteBuf |
retain()
Increases the reference count by
1. |
ByteBuf |
retain(int increment)
Increases the reference count by the specified
increment. |
protected void |
setRefCnt(int refCnt)
An unsafe operation intended for use by a subclass that sets the reference count of the buffer directly
