        public TrajectoryIteratorVector2DCPtr​(long cPtr,
                                              boolean cMemoryOwn)
      • TrajectoryIteratorVector2DCPtr

        public TrajectoryIteratorVector2DCPtr()
        Default constructor yielding a NULL-pointer.
      • TrajectoryIteratorVector2DCPtr

        public TrajectoryIteratorVector2DCPtr​(TrajectoryIteratorVector2D ptr)
        Do not take ownership of ptr.

        ptr can be null.

        The constructor is implicit on purpose.

      • 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
      • getTime

        public double getTime()
        Returns the current position (time) of the iterator
        Returns:
        The current time.
      • isEnd

        public boolean isEnd()
        Test if the end of the trajectory is reached.

        Returns:
        true if the iterator has reached the end of the trajectory false
        otherwise.
      • isBegin

        public boolean isBegin()
        Test if the beginning of the trajectory is reached.

        Returns:
