    Modifier and Type
    Method
    Description
    void
    eraseFeedbackData()
    This method must be called at the end of the edge feedback ( {@link org.eclipse.gef.editpolicies.ConnectionEndpointEditPolicy.eraseConnectionMoveFeedback(ReconnectRequest)} or {@link org.eclipse.gmf.runtime.gef.ui.internal.editpolicies.ConnectionBendpointEditPolicy.eraseConnectionFeedback(BendpointRequest, boolean)} for example).
    void
    relocate(org.eclipse.draw2d.IFigure target)
     
    void
    setFeedbackData(org.eclipse.draw2d.geometry.PointList oldPointList, org.eclipse.draw2d.geometry.Vector oldLabelOffset, boolean isEdgeWithObliqueRoutingStyle)
    This method must be called before edge feedback creation ( org.eclipse.sirius.diagram.ui.graphical.edit.policies.TreeLayoutConnectionLineSegEditPolicy#showMoveLineSegFeedback(BendpointRequest) or org.eclipse.sirius.diagram.ui.tools.internal.graphical.edit.policies.SiriusConnectionEndPointEditPolicy#showConnectionMoveFeedback(ReconnectRequest) ) for example), to initialize the data needed to compute the label offset dynamically and draw the label feedback correctly.
    The method eraseFeedbackData() must be called when edge feedback is erase.

    • setFeedbackData

      public void setFeedbackData(org.eclipse.draw2d.geometry.PointList oldPointList, org.eclipse.draw2d.geometry.Vector oldLabelOffset, boolean isEdgeWithObliqueRoutingStyle)
      This method must be called before edge feedback creation ( org.eclipse.sirius.diagram.ui.graphical.edit.policies.TreeLayoutConnectionLineSegEditPolicy#showMoveLineSegFeedback(BendpointRequest) or org.eclipse.sirius.diagram.ui.tools.internal.graphical.edit.policies.SiriusConnectionEndPointEditPolicy#showConnectionMoveFeedback(ReconnectRequest) ) for example), to initialize the data needed to compute the label offset dynamically and draw the label feedback correctly.
      The method eraseFeedbackData() must be called when edge feedback is erase.
      Parameters:
      oldPointList - The points list of the edge before to start to move it.
      oldLabelOffset - The offset of the label before to start to move the edge.
      isEdgeWithObliqueRoutingStyle - The status of the edge routing style

    • eraseFeedbackData

      public void eraseFeedbackData()
