      StateCachePtr()
      Default constructor yielding a NULL-pointer.
      StateCachePtr​(long cPtr, boolean cMemoryOwn)  
      StateCachePtr​(StateCache ptr)
      Do not take ownership of ptr.

      ptr can be null.

      The constructor is implicit on purpose.

    • Method Detail

      • delete

        public void delete()
      • deref

        public StateCache deref()
        The pointer stored in the object.
      • __ref__

        public StateCache __ref__()
        Dereferencing operator.
      • getDeref

        public StateCache getDeref()
        Member access operator.
      • equals

        public boolean equals​(StateCache p)
      • isShared

        public boolean isShared()
        check if this Ptr has shared ownership or none
        ownership
        Returns:
        true if Ptr has shared ownership, false if it has no ownership.
      • isNull

        public boolean isNull()
        checks if the pointer is null
        Returns:
        Returns true if the pointer is null
      • size

        public long size()
        An integer ID for the StateCache.

        IDs are assigned to the state data upon insertion State.
        StateCache that are not in a State have an ID of -1.

        StateCache present in different trees may have identical IDs.

        IDs are used for the efficient implementation of State. Normally,
        you should not make use of frame IDs yourself.

        Returns:
        An integer ID for the frame.

        The number of doubles allocated by this StateCache in
        each State object.

      • clone

        public StateCachePtr clone()
        this creates a deep copy of this cache
