      All Methods Static Methods Instance Methods Concrete Methods 
      Modifier and Type Method Description
      Transform3Df ddx​(double t)
      Acceleration of trajectory at time t

      Returns the acceleration of the trajectory at time t \in[startTime(), endTime()].
      void delete()  
      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.
      Transform3Df 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().
      static long getCPtr​(TrajectoryTransform3D_f obj)  
      TrajectoryIteratorTransform3D_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.
      TrajectoryIteratorTransform3D_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.
      SWIGTYPE_p_std__vectorT_rw__math__Transform3DT_float_t_t getPath​(double dt)
      Constructs a discrete path based on the trajectory.

      If uniform = true the path will be divided into the smallest number of
      uniform steps for which the time stepsize <= dt.

      If uniform = false the path is divided into steps of duration dt, except the
      last interval which may be shorter to include the end point.
      SWIGTYPE_p_std__vectorT_rw__math__Transform3DT_float_t_t getPath​(double dt, boolean uniform)
      Constructs a discrete path based on the trajectory.

      If uniform = true the path will be divided into the smallest number of
      uniform steps for which the time stepsize <= dt.

      If uniform = false the path is divided into steps of duration dt, except the
      last interval which may be shorter to include the end point.
      double startTime()
      Returns the startTime of the trajectory
      Transform3Df x​(double t)
      Position of trajectory at time t

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