Method Summary

Modifier and Type	Method and Description
private void	countCallCandidates(NodeTraversal t, Node callNode) Counts references to property names that occur in a special function call.
private void	countPropertyOccurrence(java.lang.String name) Increments the occurrence count for a property name.
private void	maybeMarkCandidate(Node n) If a property node is eligible for renaming, stashes a reference to it and increments the property name's access count.
void	visit(NodeTraversal t, Node n, Node parent) Visits a node in postorder (after its children have been visited).

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).

maybeMarkCandidate

private void maybeMarkCandidate(Node n)

If a property node is eligible for renaming, stashes a reference to it and increments the property name's access count.

Parameters:

n - The STRING node for a property

countCallCandidates

private void countCallCandidates(NodeTraversal t,
                                 Node callNode)

Counts references to property names that occur in a special function call.

Parameters:

callNode - The CALL node for a property

t - The traversal

countPropertyOccurrence

private void countPropertyOccurrence(java.lang.String name)

Increments the occurrence count for a property name.

Parameters:

name - The property name
