Constructor Details

ZeroXContainerCFABuilder

public ZeroXContainerCFABuilder(IClassHierarchy cha,
 AnalysisOptions options,
 IAnalysisCacheView cache,
 ContextSelector appContextSelector,
 SSAContextInterpreter appContextInterpreter,
 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:

IllegalArgumentException - if options is null

Method Details

makeContainerContextSelector

protected ContextSelector makeContainerContextSelector(IClassHierarchy cha,
 ZeroXInstanceKeys keys)

Returns:

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