Constructor	Description
JavaScriptScopeMappingInstanceKeys(IClassHierarchy cha, PropagationCallGraphBuilder builder, InstanceKeyFactory basic)

Method Summary

Modifier and Type	Method	Description
protected Collection<CGNode>	getConstructorCallers(ScopeMappingInstanceKeys.ScopeMappingInstanceKey smik, Pair<String,String> name)	get the CGNodes corresponding to the method that invoked the constructor for smik
protected AstMethod.LexicalParent[]	getParents(InstanceKey base)
protected boolean	isTrueConstructorCall(Pair<String,String> name, CGNode callerOfConstructor)
protected boolean	needsScopeMappingKey(InstanceKey base)	does base require a scope mapping key? Typically, true if base is allocated in a nested lexical scope, to handle the case of base being a function that performs closure accesses

Method Details

getParents

protected AstMethod.LexicalParent[] getParents(InstanceKey base)

needsScopeMappingKey

protected boolean needsScopeMappingKey(InstanceKey base)

Description copied from class: ScopeMappingInstanceKeys

does base require a scope mapping key? Typically, true if base is allocated in a nested lexical scope, to handle the case of base being a function that performs closure accesses

Specified by:

needsScopeMappingKey in class ScopeMappingInstanceKeys

getConstructorCallers

protected Collection<CGNode> getConstructorCallers(ScopeMappingInstanceKeys.ScopeMappingInstanceKey smik,
 Pair<String,String> name)

Description copied from class: ScopeMappingInstanceKeys

get the CGNodes corresponding to the method that invoked the constructor for smik

Specified by:

getConstructorCallers in class ScopeMappingInstanceKeys

isTrueConstructorCall

protected boolean isTrueConstructorCall(Pair<String,String> name,
 CGNode callerOfConstructor)

Specified by:

isTrueConstructorCall in class ScopeMappingInstanceKeys

Parameters:

name - the variable name and creator pair

callerOfConstructor - the purported caller of the constructor

Returns:

whether this is a real constructor call or an artifact of function pointers (always true for lexical scoping in Java)
