Throws:

ExecutionException

setLabelsToUpdate

public void setLabelsToUpdate(org.eclipse.gmf.runtime.diagram.ui.editparts.ConnectionEditPart connectionEditPart)

Set labels to update according to a connectionEditPart (all labels of this connection will be update).
This method must be called after having called the setNewPointList(PointList) method.

Parameters:

connectionEditPart - The connection from which to get the potential three labels to update

setLabelsToUpdate

public void setLabelsToUpdate(org.eclipse.gmf.runtime.diagram.ui.editparts.ConnectionEditPart connectionEditPart,
                              org.eclipse.draw2d.geometry.PointList originalPoints)

Set labels to update according to a connectionEditPart (all labels of this connection will be update). This method must be used if the edge figure is updated (through feedback) during the move. Indeed, in this case, we can not use the figure to retrieve the old points.
This method must be called after having called the setNewPointList(PointList) method.

Parameters:

connectionEditPart - The connection from which to get the potential three labels to update

originalPoints - The points of the edge before the move.
