de.aristaflow.adept2.core.changeoperations.MoveNodes

public class MoveNodes
extends java.lang.Object

Change operation for moving nodes. Call isValidMoveBlock to determine if a given block is a valid move block. Then call isPossible to check the validity of the target point for the move operation as well. If isPossible returns true, call perform operation to execute the change. TODO Refactor; use a common interface for change operations.
