    • getPoint

      public Point2D getPoint()
      Description copied from interface: Handler

      Generic method of getting the 2D point that represents a handler of a geometry.

      Each handler of each geometry adapts this method to its own behavior in that geometry, that implies that could not be implemented.

      Specified by:
      getPoint in interface Handler
      Returns:
      point 2D that represents this handler of geometry

    • select

      public void select(boolean b)
      Sets the state of the handler. True if is selected, false if it's not.
      Parameters:
      b - true if the handler is selected, false otherwise

    • isSelected

      public boolean isSelected()
      Returns the state of the handler. True if is selected, false if it's not.
      Returns:
      true if the handler is selected,false otherwise

    • equalsPoint

      public boolean equalsPoint(Object obj)
      Description copied from interface: Handler

      Returns true if the object is a Handler and has the same coordinates as this one.

      Specified by:
      equalsPoint in interface Handler
      Parameters:
      obj - the reference object with which to compare
      Returns:
      true if this object is the same as the obj argument; false otherwise
