public abstract class GFAbstractPointListShape extends GFAbstractShape
An abstract class for those Graphiti Shapes, which are based on a list of points, e.g. polyline and polygon.This abstract class only adds the point-list and the setter/getter methods for it. It also takes care to reset the bounds and repaint the figure when the point-list changes. But it does not add any details how the Shape is outlined.

GFAbstractPointListShape
public GFAbstractPointListShape(IPictogramElementDelegate pictogramElementDelegate, GraphicsAlgorithm graphicsAlgorithm)
Creates a new GFAbstractPointListShape.- Parameters:
pictogramElementDelegate
- The PictogramElementDelegate which provides the GraphicsAlgorithm.graphicsAlgorithm
- The GraphicsAlgorithm which provides the values to paint this Shape.
-
-
Method Detail
-
getPoints
public final org.eclipse.draw2d.geometry.PointList getPoints()
Returns the points in this Shape by reference. If the returned list is modified, this Shape must be informed by callingsetPoints(PointList)
. Failure to do so will result in layout and paint problems.- Returns:
- The points in this Shape by reference.
-
getStart
public org.eclipse.draw2d.geometry.Point getStart()
Returns the first point in the point-list.- Returns:
- the first point in the point-list.
-
getEnd
public org.eclipse.draw2d.geometry.Point getEnd()
Returns the last point in the point-list.- Returns:
- the last point in the point-list.
-
addPoint
public void addPoint(org.eclipse.draw2d.geometry.Point pt)
Adds the passed point to the point-list. This method results in a recalculation of the Shapes bounding box.- Parameters:
pt
- The Point to be added to the point-list.
-
insertPoint
public void insertPoint(org.eclipse.draw2d.geometry.Point pt, int index)
Inserts a given point at a specified index in the point-list. This method results in a recalculation of the Shapes bounding box.- Parameters:
pt
- The point to be added.index
- the position in the point-list where the point is to be added.
-
setPoint
public void setPoint(org.eclipse.draw2d.geometry.Point pt, int index)
Overwrites the point atindex
with the Pointpt
. If you're going to set multiple Points, usesetPoints(PointList)
. This method results in a recalculation of the Shapes bounding box.- Parameters:
pt
- The point to set.index
- The index, at which to set the point.
-
setPoints
public void setPoints(org.eclipse.draw2d.geometry.PointList points)
Sets the list of points to be used by this Shape by reference. The previous PointList used by this Shape is not used anymore. This method results in a recalculation of the Shapes bounding box.- Parameters:
points
- The new PointList used by this Shape.
-
setStart
public void setStart(org.eclipse.draw2d.geometry.Point start)
Sets the start point of the point-list. This method results in a recalculation of the Shapes bounding box.- Parameters:
start
- The point that will become the first point in the point-list.
-
setEnd
public void setEnd(org.eclipse.draw2d.geometry.Point end)
Sets the end point of the point-list. This method results in a recalculation of the Shapes bounding box.- Parameters:
end
- The point that will become the last point in the point-list.
-
removePoint
public void removePoint(int index)
Removes a point at a given index from the point-list. This method results in a recalculation of the Shapes bounding box.- Parameters:
index
- The position of the point to be removed.
-
removeAllPoints
public void removeAllPoints()
This method results in a recalculation of the Shapes bounding box. Removes all points from the point-list.
