- com.ibm.wala.cast.ipa.callgraph.ScopeMappingInstanceKeys.ScopeMappingInstanceKey

All Implemented Interfaces:

ContextItem, InstanceKey

Enclosing class:

ScopeMappingInstanceKeys
```
public class ScopeMappingInstanceKeys.ScopeMappingInstanceKey
extends Object
implements InstanceKey
```
An InstanceKey carrying information about which CGNodes represent lexical parents of the allocating CGNode. The fact that we discover at most one CGNode per lexical parent relies on the following property: in a call graph, the contexts used for a nested function can be finer than those used for the containing function, but _not_ coarser. This ensures that there is at most one CGNode corresponding to a lexical parent (e.g., we don't get two clones of function f1() invoking a single CGNode representing nested function f2()) Note that it is possible to not find a CGNode corresponding to some lexical parent; this occurs when a deeply nested function is returned before being invoked, so some lexical parent is no longer on the call stack when the function is allocated. See test case nested.js.

    Description copied from interface: InstanceKey
    
    Get the creation sites of this, i.e., the statements that may allocate objects represented by this. A creation site is a pair (n,s), where n is the containing CGNode in the given CallGraph CG and s is the allocating NewSiteReference.
