Interface DependencyGraph.Visitor

All Known Implementing Classes:

DependencyGraph.AbstractVisitor

Enclosing interface:

DependencyGraph

public static interface DependencyGraph.Visitor

Method Summary

Collection	getResults() Returns the objects that the vistor collected during the traversal.
boolean	visit(Persistable node, DependencyGraph.Dependency dependency, Iterated fromNode, boolean previouslyVisited) Decides whether or not to continue the traversal upwards or downwards starting with the given node.

Method Detail

visit

public boolean visit(Persistable node,
                     DependencyGraph.Dependency dependency,
                     Iterated fromNode,
                     boolean previouslyVisited)

Decides whether or not to continue the traversal upwards or downwards starting with the given node. Notes: a) The "node" may be either an iteration or a master depending upon what the configuration spec selected. b) The immediate dependents of the root objects are the first "nodes" that the Vistor will visit. The Vistor will visit a root object only if it is a dependent of another root object (or a circular dependency exists). c) An EPM document may have circular dependencies. If a Vistor elects to visit previously visited nodes, it must check for circular dependencies otherwise an infinite loop may result.

Supported API: false
