Provides an implementation of global (interprocedural) data flow. This file
re-exports the local (intraprocedural) data flow analysis from
and adds a global analysis, mainly exposed through the
This file exists in several identical copies, allowing queries to use
Configuration classes that depend on each other without
introducing mutual recursion among those configurations.
Basic definitions for use in the data flow library.

A configuration of interprocedural data flow analysis. This defines sources, sinks, and any other configurable aspect of the analysis. Each use of the global data flow library must define its own unique extension of this abstract class. To create a configuration, extend this class with a subclass whose characteristic predicate is a unique singleton string. For example, write
Provides the query predicates needed to include a graph in a path-problem query.
