Class IntentContextInterpreter

java.lang.Object

com.ibm.wala.dalvik.ipa.callgraph.propagation.cfa.IntentContextInterpreter

All Implemented Interfaces:

com.ibm.wala.ipa.callgraph.cha.CHAContextInterpreter, com.ibm.wala.ipa.callgraph.propagation.rta.RTAContextInterpreter, com.ibm.wala.ipa.callgraph.propagation.SSAContextInterpreter

public class IntentContextInterpreter
extends Object
implements com.ibm.wala.ipa.callgraph.propagation.SSAContextInterpreter

An SSAContextInterpreter that redirects functions that start Android-Components. The Starter-Functions (listed in IntentStarters) are replaced by a Model that emulates Android Lifecycle based on their Target (Internal, External, ...): A wrapper around the single models is generated dynamically (by the models themselves) to resemble the signature of the replaced function. Methods are replacement by generating a adapted Intermediate Representation of this function on every occurrence of a call to it.
