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

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

checkNamingAndAssignmentUsage

private void checkNamingAndAssignmentUsage(NodeTraversal t,
                                           Node n)

checkName

private void checkName(NodeTraversal t,
                       Node node)

checkDuplicateEnumValues

private void checkDuplicateEnumValues(NodeTraversal t,
                                      Node n)
