com.ibm.wala.ipa.callgraph.propagation.rta.DelegatingExplicitCallGraph.DelegatingCGNode

All Implemented Interfaces:

CGNode, ContextItem, IClassHierarchyDweller, INodeWithNumber

Enclosing class:

DelegatingExplicitCallGraph

public class DelegatingExplicitCallGraph.DelegatingCGNode
extends ExplicitCallGraph.ExplicitNode

In this implementation, super.targets is a mapping from call site -> Object, where Object is a

• CGNode if we've discovered exactly one target for the site
• or an IntSet of node numbers if we've discovered more than one target for the site.
• a CallSite if we're delegating these edges to another node
