visitCall

private void visitCall(NodeTraversal t,
                       Node n)

dereference

private JSType dereference(JSType type)

Dereference a type, autoboxing it and filtering out null. From CheckAccessControls

visitFunction

public void visitFunction(NodeTraversal t,
                          Node n)

visitAssign

public void visitAssign(NodeTraversal t,
                        Node n)

visitReturn

private void visitReturn(NodeTraversal t,
                         Node n)

eventfulObjectDisposed

private void eventfulObjectDisposed(NodeTraversal t,
                                    Node variableNode)

enterScope

public void enterScope(NodeTraversal t)

Description copied from interface: NodeTraversal.ScopedCallback

Called immediately after entering a new scope. The new scope can be accessed through t.getScope()

Specified by:

enterScope in interface NodeTraversal.ScopedCallback

exitScope

public void exitScope(NodeTraversal t)

Description copied from interface: NodeTraversal.ScopedCallback

Called immediately before exiting a scope. The ending scope can be accessed through t.getScope()

Specified by:

exitScope in interface NodeTraversal.ScopedCallback

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
