Class DefaultDependencyResolver

java.lang.Object

com.google.javascript.jscomp.deps.DefaultDependencyResolver

All Implemented Interfaces:

DependencyResolver

public final class DefaultDependencyResolver
extends java.lang.Object
implements DependencyResolver

Class for resolving Closure dependencies. Given a valid deps.js file the dependency tree is parsed and stored in memory. The DependencyResolver can then be used to calculate the full list of transitive dependencies from: a block of code ( getDependencies(String)), or a list of symbols getDependencies(Collection).
