Class ClosureCheckModule

java.lang.Object

com.google.javascript.jscomp.NodeTraversal.AbstractModuleCallback

com.google.javascript.jscomp.ClosureCheckModule

All Implemented Interfaces:

CompilerPass, HotSwapCompilerPass, NodeTraversal.Callback, NodeTraversal.ScopedCallback

public final class ClosureCheckModule
extends NodeTraversal.AbstractModuleCallback
implements HotSwapCompilerPass

Checks that goog.module() is used correctly.

Note that this file only does checks that can be done per-file. Whole program checks happen during goog.module rewriting, in ClosureRewriteModule.

Method Detail

process

public void process(Node externs,
                    Node root)

Description copied from interface: CompilerPass

Process the JS with root node root. Can modify the contents of each Node tree

Specified by:

process in interface CompilerPass

Parameters:

externs - Top of external JS tree

root - Top of JS tree

hotSwapScript

public void hotSwapScript(Node scriptRoot,
                          Node originalRoot)

Description copied from interface: HotSwapCompilerPass

Process the JS with root node root. This is supposed to be significantly faster compared to corresponding full-compiler passes.

Specified by:

hotSwapScript in interface HotSwapCompilerPass

Parameters:

scriptRoot - Root node corresponding to the file that is modified, should be of type Token.SCRIPT.

originalRoot - Root node corresponding to the original version of the file that is modified. Should be of type token.SCRIPT.

enterModule

public void enterModule(NodeTraversal t,
                        Node scopeRoot)

Description copied from class: NodeTraversal.AbstractModuleCallback

Called immediately after entering a module.

Specified by:

enterModule in class NodeTraversal.AbstractModuleCallback

exitModule

public void exitModule(NodeTraversal t,
                       Node scopeRoot)

Description copied from class: NodeTraversal.AbstractModuleCallback

Called immediately before exiting a module.

Specified by:

exitModule in class NodeTraversal.AbstractModuleCallback

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).

Specified by:

visit in interface NodeTraversal.Callback
