All Implemented Interfaces:

Method Detail

processFile

public void processFile(Node root)

visit

public void visit(NodeTraversal t,
         Node n,
         Node parent)

Description copied from interface: NodeTraversal.Callback

Visits a node in postorder (after its children have been visited). A node is visited only if all its parents should be traversed (NodeTraversal.Callback.shouldTraverse(NodeTraversal, Node, Node)).

Implementations can have side effects (e.g. modifying the parse tree).

toModuleName

public static String toModuleName(String filename)

Turns a filename into a JS identifier that is used for moduleNames in rewritten code. For example, "./foo.js" transformed to "foo".
