Detailed Description

A base class to help implement the function alias analysis results concept.

Because of the nature of many alias analysis implementations, they often only implement a subset of the interface. This base class will attempt to implement the remaining portions of the interface in terms of simpler forms of the interface where possible, and otherwise provide conservatively correct fallback implementations.

Implementors of an alias analysis should derive from this class, and then override specific methods that they wish to customize. There is no need to use virtual anywhere.
