Class SourceInformationAnnotator

java.lang.Object

com.google.javascript.jscomp.NodeTraversal.AbstractPostOrderCallback

com.google.javascript.jscomp.SourceInformationAnnotator

All Implemented Interfaces:

NodeTraversal.Callback

class SourceInformationAnnotator
extends NodeTraversal.AbstractPostOrderCallback

Annotates nodes with information from their original input file before the compiler performs work that changes this information (such as its original location, its original name, etc). Information saved: - Annotates all NAME nodes with an ORIGINALNAME_PROP indicating its original name. - Annotates all string GET_PROP nodes with an ORIGINALNAME_PROP. - Annotates all OBJECT_LITERAL unquoted string key nodes with an ORIGINALNAME_PROP. - Annotates all FUNCTION nodes with an ORIGINALNAME_PROP indicating its nearest original name.

Method Detail

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).

setOriginalName

static void setOriginalName(Node n,
                            java.lang.String name)
