      Description copied from interface: ReferenceCounted
      Returns the reference count of this object. If 0, it means this object has been deallocated.
      Specified by:
      refCnt in interface ReferenceCounted

    • setRefCnt

      protected void setRefCnt(int refCnt)
      An unsafe operation intended for use by a subclass that sets the reference count of the object directly

    • retain

      public ReferenceCounted retain()
      Description copied from interface: ReferenceCounted
      Increases the reference count by 1.
      Specified by:

    • retain

      public ReferenceCounted retain(int increment)
      Description copied from interface: ReferenceCounted
      Increases the reference count by the specified increment.

    • touch

      public ReferenceCounted 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

    • 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

    • deallocate

      protected abstract void deallocate()
