    • getBox

      protected org.eclipse.draw2d.geometry.Rectangle getBox()
      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

    • getLocation

      public org.eclipse.draw2d.geometry.Point getLocation(org.eclipse.draw2d.geometry.Point reference)
      Description copied from class: ChopboxAnchorFixed
      CHANGED: if the reference is in the center of the figure, the result was not correct. This method has to be kept in sync with GefService.getChopboxLocationOnBox(Point, Rectangle).
      Specified by:
      getLocation in interface org.eclipse.draw2d.ConnectionAnchor
      Overrides:
      getLocation in class ChopboxAnchorFixed

    • getLocation

      protected org.eclipse.draw2d.geometry.Point getLocation(org.eclipse.draw2d.geometry.Point ownReference, 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
