Class NodeTraversal.AbstractModuleCallback

java.lang.Object

com.google.javascript.jscomp.NodeTraversal.AbstractModuleCallback

All Implemented Interfaces:

NodeTraversal.Callback

Direct Known Subclasses:

ClosureCheckModule

Enclosing class:

NodeTraversal

public abstract static class NodeTraversal.AbstractModuleCallback
extends java.lang.Object
implements NodeTraversal.Callback

Abstract callback that knows when goog.provide, goog.module, and ES modules are entered and exited. This includes both whole file modules and bundled modules.

Method Detail

enterModule

protected void enterModule(ModuleMetadataMap.ModuleMetadata currentModule,
                           Node moduleScopeRoot)

exitModule

protected void exitModule(ModuleMetadataMap.ModuleMetadata oldModule,
                          Node moduleScopeRoot)

shouldTraverse

public final boolean shouldTraverse(NodeTraversal t,
                                    Node n,
                                    Node parent)

Description copied from interface: NodeTraversal.Callback

Visits a node in pre order (before visiting its children) and decides whether this node's children should be traversed. If children are traversed, they will be visited by NodeTraversal.Callback.visit(NodeTraversal, Node, Node) in postorder.

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

Specified by:

shouldTraverse in interface NodeTraversal.Callback

Returns:

whether the children of this node should be visited

shouldTraverse

protected boolean shouldTraverse(NodeTraversal t,
                                 Node n,
                                 @Nullable
                                 ModuleMetadataMap.ModuleMetadata currentModule,
                                 @Nullable
                                 Node moduleScopeRoot)

visit

public final 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

visit

protected void visit(NodeTraversal t,
                     Node n,
                     @Nullable
                     ModuleMetadataMap.ModuleMetadata currentModule,
                     @Nullable
                     Node moduleScopeRoot)
