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).

handleGetProp

private void handleGetProp(NodeTraversal t,
                           Node n)

handleObjectLit

private void handleObjectLit(NodeTraversal t,
                             Node n)

printErrorLocations

private void printErrorLocations(java.util.List<java.lang.String> errors,
                                 JSType t)

processProperty

private JSType processProperty(NodeTraversal t,
                               DisambiguateProperties.Property prop,
                               JSType type,
                               JSType relatedType)

Processes a property, adding it to the list of properties to rename.

Returns:

a representative type for the property reference, which will be the highest type on the prototype chain of the provided type. In the case of a union type, it will be the highest type on the prototype chain of one of the members of the union.
