Description copied from class: BendpointEditPolicyFixed

Implement this method to return a Command that will delete a bendpoint.

Specified by:

getDeleteBendpointCommand in class BendpointEditPolicyFixed

Parameters:

request - the BendpointRequest

Returns:

a Command to delete a bendpoint

getMoveBendpointCommand

protected org.eclipse.gef.commands.Command getMoveBendpointCommand(org.eclipse.gef.requests.BendpointRequest request)

Description copied from class: BendpointEditPolicyFixed

Implement this method to return a Command that will move a bendpoint.
