Package de.xima.fc.workflow.designer.helper

Class AssociateHelper

java.lang.Object

de.xima.fc.workflow.designer.helper.AssociateHelper

public final class AssociateHelper
extends Object

Contains all methods that associate derived quantities with the current state.

By providing the proper dependencies, the derived quantities are recomputed only when that dependency has changed. For example, we only need to recompute the flow analysis when the structure of the node has changed, e.g. when a node was added or moved.

Since:

7.0.0
