        Gets the anchors associated figure's bounding box in absolute coordinates.
        Overrides:
        getBox in class org.eclipse.draw2d.ChopboxAnchor
        Returns:
        a Rectangle that is the bounding box of the owner figure in absolute coordinates. also regards the indents

                                                        org.eclipse.draw2d.geometry.Point foreignReference)
        Calculates the location of the anchor depending on the anchors own reference and foreign reference points
        Parameters:
        ownReference - - the own reference of the anchor
        foreignReference - - foreign reference that comes in
        Returns:
        the location of the anchor depending on the anchors own reference and foreign reference points

      • pickClosestPoint

        public static org.eclipse.draw2d.geometry.Point pickClosestPoint​(org.eclipse.draw2d.geometry.PointList points,
                                                                 org.eclipse.draw2d.geometry.Point p)
        Assumption: Points in the PointList and Point p lie on the same line. Returns the Point from the PointList closest to
        Parameters:
        p -
        points - - the list of points to select the result from
        p - - the point to which the closest point must be found
        p -
        Returns:
        the Point from the PointList closest to

      • getIntersectionPoints

        protected org.eclipse.draw2d.geometry.PointList getIntersectionPoints​(org.eclipse.draw2d.geometry.Point ownReference,
                                                                      org.eclipse.draw2d.geometry.Point foreignReference)
        Calculates intersection points of the figure and the line that passes through ownReference and foreignReference points
        Parameters:
        ownReference - the reference Point on or inside the shape that is being anchored to.
        foreignReference - the outside reference Point point that is the terminal end of the line formed by the two parameters.
        Returns:
        intersection points of the figure and the line that passes through ownReference and foreignReference points

      • getClosedPointListOfPointListShape

        protected org.eclipse.draw2d.geometry.PointList getClosedPointListOfPointListShape()
        Returns the list of all the vertices of the figure. The created list must form a polygon, i.e. closed polyline, for figures hence the starting and ending points must be the same
        Returns:
        the PointList list of all the vertices of the figure.

      • getAnchorRelativeLocation

        public static org.eclipse.draw2d.geometry.PrecisionPoint getAnchorRelativeLocation​(org.eclipse.draw2d.geometry.Point p,
                                                                                   org.eclipse.draw2d.geometry.Rectangle bounds)
        Calculates the relative location of the reference point with respect to the bounds of the figure. If point p is not inside of the figure's bounds then the point is mapped on the bounds and the point relative location is calculated
        Parameters:
        p - the Point that is relative coordinates of the point
        Returns:
        PrecisionPoint, i.e. the relative reference for SlidableAnchor
