Class SimpleDefinitionFinder

java.lang.Object

com.google.javascript.jscomp.SimpleDefinitionFinder

All Implemented Interfaces:

CompilerPass

public class SimpleDefinitionFinder
extends Object
implements CompilerPass

Simple name-based definition gatherer that implements DefinitionProvider. It treats all variable writes as happening in the global scope and treats all objects as capable of having the same set of properties. The current implementation only handles definitions whose right hand side is an immutable value or function expression. All complex definitions are treated as unknowns.
