Nested Class Summary

static interface

AllCallers.MethodSet MethodSet defines the interface whose method select is used in getCallers as a predicate.

Constructor Summary

AllCallers(ClassHierarchy ch, HCodeFactory hcf)
Creates an AllCallers object using the specified ClassHierarchy.

Method Summary

Constructor Detail

AllCallers

public AllCallers(ClassHierarchy ch,
                  HCodeFactory hcf)

Creates an AllCallers object using the specified ClassHierarchy. Currently, hcf must be a code factory that generates quad-no-ssa or quad-ssi form because the dual of the call graph is built using CallGraph.

AllCallers

public AllCallers(CallGraph cg)

Creates an AllCallers object that is the dual of the callgraph cg (of type harpoon.Analysis.Quads.CallGraoh).
