org.asem.eclipse.mii.model.commands.ConnectionReconnectCommand

A command to reconnect a connection to a different start point or end point. The command can be undone or redone.

This command is designed to be used together with a GraphicalNodeEditPolicy. To use this command propertly, following steps are necessary:

Create a subclass of GraphicalNodeEditPolicy.
Override the getReconnectSourceCommand(...) method. Here you need to obtain the Connection model element from the ReconnectRequest, create a new ConnectionReconnectCommand, set the new connection source by calling the setNewSource(Shape) method and return the command instance.
Override the getReconnectTargetCommand(...) method.

target

setNewTarget(Shape)

@see org.eclipse.gef.examples.shapes.parts.ShapeEditPart#createEditPolicies() for an example of the above procedure. @see org.eclipse.gef.editpolicies.GraphicalNodeEditPolicy @see #setNewSource(Shape) @see #setNewTarget(Shape) @author Elias Volanakis
