Class ProcessEs6Modules

java.lang.Object

com.google.javascript.jscomp.NodeTraversal.AbstractPostOrderCallback

com.google.javascript.jscomp.ProcessEs6Modules

All Implemented Interfaces:

NodeTraversal.Callback

public final class ProcessEs6Modules
extends NodeTraversal.AbstractPostOrderCallback

Rewrites a ES6 module into a form that can be safely concatenated. Note that we treat a file as an ES6 module if it has at least one import or export statement.

ProcessEs6Modules

public ProcessEs6Modules(Compiler compiler)

Creates a new ProcessEs6Modules instance which can be used to rewrite ES6 modules to a concatenable form.

Method Detail

processFile

public void processFile(Node root,
                        boolean forceRewrite)

If a file contains an ES6 "import" or "export" statement, or the forceRewrite option is true, rewrite the source as a module.

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).
