Class VariableReferenceCheck.ReferenceCheckingBehavior.ShallowReferenceCollector

java.lang.Object

com.google.javascript.jscomp.NodeTraversal.AbstractShallowCallback

com.google.javascript.jscomp.VariableReferenceCheck.ReferenceCheckingBehavior.ShallowReferenceCollector

All Implemented Interfaces:

NodeTraversal.Callback

Enclosing class:

VariableReferenceCheck.ReferenceCheckingBehavior

private class VariableReferenceCheck.ReferenceCheckingBehavior.ShallowReferenceCollector
extends NodeTraversal.AbstractShallowCallback

Do a shallow check since cases like: function f(y = () => x, x = 5) { return y(); } is legal. We are going to miss cases like: function f(y = (() => x)(), x = 5) { return y(); } but this should be rare.

public void visit(NodeTraversal t,

                  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).
