  com.ibm.wala.ipa.callgraph.propagation.ConcreteTypeKey

All Implemented Interfaces:

ContextItem, InstanceKey

public final class ConcreteTypeKey
extends java.lang.Object
implements InstanceKey

An instance key which represents a unique set for each concrete type

Constructor Summary

getInstanceKeysForPEI

public static InstanceKey[] getInstanceKeysForPEI(SSAInstruction pei,
                                                  IR ir,
                                                  IClassHierarchy cha)

Parameters:

pei - a PEI instruction

cha - governing class hierarchy

Returns:

a set of ConcreteTypeKeys that represent the exceptions the PEI may throw.

Throws:

java.lang.IllegalArgumentException - if pei is null
