    • Method Summary

      All Methods Static Methods Instance Methods Concrete Methods 
      Modifier and Type Method Description
      TrajectoryVector2D_f __ref__()
      Dereferencing operator.
      Vector2Df ddx​(double t)
      Acceleration of trajectory at time t

      Returns the acceleration of the trajectory at time t \in[startTime(), endTime()].
      void delete()  
      TrajectoryVector2D_f deref()
      The pointer stored in the object.
      double duration()
      Total duration of the trajectory.

      The duration of the Trajectory corresponds to the time it takes to
      run through it.

      If the trajectory is empty, then -1 is returned.
      Vector2Df dx​(double t)
      Velocity of trajectory at time t

      Returns the velocity of the trajectory at time t \in[startTime(), endTime()].
      double endTime()
      Returns the endTime of the trajectory.

      The end time equals startTime() + duration().
      boolean equals​(TrajectoryVector2D_f p)  
      static long getCPtr​(TrajectoryVector2D_fCPtr obj)  
      TrajectoryVector2D_f getDeref()
      Member access operator.
      TrajectoryIteratorVector2D_fPtr getIterator()
      Returns a bi-directional interator for running through the trajectory.

      For some trajectory types it may be significantly more efficient to run through
      using an iterator, rather than using random access.


      Pointer to the iterator.
      TrajectoryIteratorVector2D_fPtr getIterator​(double dt)
      Returns a bi-directional interator for running through the trajectory.

      For some trajectory types it may be significantly more efficient to run through
      using an iterator, rather than using random access.
      boolean isNull()
      checks if the pointer is null
      boolean isShared()
      check if this Ptr has shared ownership or none
      ownership
      double startTime()
      Returns the startTime of the trajectory
      Vector2Df x​(double t)
      Position of trajectory at time t

      Returns the position of the trajectory at time t \in[startTime(), endTime()].

      • TrajectoryVector2D_fCPtr

        public TrajectoryVector2D_fCPtr​(long cPtr,
                                boolean cMemoryOwn)

      • TrajectoryVector2D_fCPtr

        public TrajectoryVector2D_fCPtr()
        Default constructor yielding a NULL-pointer.

      • TrajectoryVector2D_fCPtr

        public TrajectoryVector2D_fCPtr​(TrajectoryVector2D_f ptr)
        Do not take ownership of ptr.

        ptr can be null.

        The constructor is implicit on purpose.

      • delete

        public void delete()

      • 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

      • x

        public Vector2Df x​(double t)
        Position of trajectory at time t

        Returns the position of the trajectory at time t \in[startTime(), endTime()].

        Parameters:
        t - [in] time between startTime() and endTime()
        Returns:
        Position

      • dx

        public Vector2Df dx​(double t)
        Velocity of trajectory at time t

        Returns the velocity of the trajectory at time t \in[startTime(), endTime()].

        Parameters:
        t - [in] time between startTime() and endTime()
        Returns:

        public TrajectoryIteratorVector2D_fPtr getIterator​(double dt)
        Returns a bi-directional interator for running through the trajectory.

        For some trajectory types it may be significantly more efficient to run through
        using an iterator, rather than using random access.

        Parameters:
