    • invalidate

      protected void invalidate()

    • calculateBounds

      protected void calculateBounds(ILcd2DEditableBounds aBoundsSFCT)
      This method should compute the bounds of the polypoint. The resulting ILcd2DEditableBounds should be stored in aBoundsSFCT.
      Parameters:
      aBoundsSFCT - assumes the location and the width and height of the bounds of the polypoint.

    • getBounds

      public ILcdBounds getBounds()
      Description copied from interface: ILcdBounded
      Returns the ILcdBounds by which the geometry of this ILcdBounded object is bounded.

      If the geometry does not allow retrieving valid bounds (for example a polyline with 0 points) the return value is unspecified. It is highly recommended to return an undefined bounds. You can create undefined bounds using the default constructors of TLcdLonLatBounds or TLcdXYBounds.

      Specified by:
      getBounds in interface ILcdBounded
      Returns:
      the ILcdBounds by which the geometry of this ILcdBounded object is bounded.

    • calculateFocusPoint

      protected void calculateFocusPoint(ILcd2DEditablePoint aFocusPointSFCT)
      Computes the focus point as the center of the bounding box. The resulting ILcd2DEditablePoint is stored in aFocusPoint.
      Parameters:
      aFocusPointSFCT - output parameter, will contain the location of the focus point.

    • getFocusPoint

      public ILcdPoint getFocusPoint()
      Description copied from interface: ILcdShape
      Returns the focus point of this ILcdShape.
      Specified by:
      getFocusPoint in interface ILcdShape
      Returns:
      the focus point of this ILcdShape.

    • contains2D

      public boolean contains2D(double aX, double aY)

      Parameters:
      aX - the x coordinate of the point.
      aY - the y coordinate of the point.

      equals in class ALcdShape
      Parameters:
      aObject - the Object to compare to.
      Returns:
      true if aObject is an ILcd2DEditablePolypoint object with a point list in which the corresponding points have the same 3D coordinates, false otherwise.

    • clone

      public Object clone()
      Description copied from class: ALcdShape
      Creates and returns a copy of this object, by delegating to Object.clone(). Extensions should delegate to this implementation with super.clone(), in order to create an object instance of the right type, with all fields copied. They then should explicitly clone any non-primitive fields for which a deeper clone is required.
      Specified by:
      clone in interface ILcdCloneable
      Overrides:
      clone in class ALcdShape

    • hashCode

      public int hashCode()
      Description copied from class: ALcdShape
      The hash code of this shape is the hash code of its class, in order to be consistent with the ALcdShape.equals(Object) method. Extensions should refine this implementation, based on their properties.
      Overrides:
      hashCode in class ALcdShape

    • createPoint

      protected abstract ILcd2DEditablePoint createPoint()
      Creates an uninitialized ILcd2DEditablePoint point of a type compatible with the concrete implementation of this class (geodesic/cartesian). The created point will be updated and returned by the getPoint(int) and getFocusPoint() methods.

    • createBounds

      protected abstract ILcd2DEditableBounds createBounds()
      Creates an uninitialized ILcd2DEditableBounds object of a type compatible with the concrete implementation of this class. This bounds object will be updated and returned by the getBounds() method.
