de.aristaflow.adept2.model.processmodel.tools.NodeRelations

public class NodeRelations
extends Object

Class which allows for work on execution orders between nodes. FIXME must handle or join of and-or-blocks like and-joins(!) Requires: correct branch IDs, topological order.

public NodeRelations(Template template)

Create a new NodeRelations object for the given template.

Parameters:

template -

Method Detail

getNodeRelation

public NodeRelations.NodeRelation getNodeRelation(int nodeID1,
                                                  int nodeID2)

Get the BEFORE relation between the given nodes, or what the relation is like, if node1 is not before node2.

Parameters:

nodeID1 - The first node, preferably it is before node2.
