Constructor Detail

ZeroXContainerCFABuilder

public ZeroXContainerCFABuilder(IClassHierarchy cha,
                                AnalysisOptions options,
                                AnalysisCache cache,
                                ContextSelector appContextSelector,

                                int instancePolicy)

Parameters:

cha - governing class hierarchy

options - call graph construction options

appContextSelector - application-specific logic to choose contexts

appContextInterpreter - application-specific logic to interpret a method in context

Throws:

java.lang.IllegalArgumentException - if options is null

Method Detail

makeContainerContextSelector

protected ContextSelector makeContainerContextSelector(IClassHierarchy cha,
                                                       ZeroXInstanceKeys keys)

Returns:

an object which creates contexts for call graph nodes based on the container disambiguation policy
