public class PropertyReadExpander
extends CAstRewriter<com.ibm.wala.cast.js.translator.PropertyReadExpander.RewriteContext,com.ibm.wala.cast.js.translator.PropertyReadExpander.ExpanderKey>

Transforms property reads to make prototype chain operations explicit. Each read is converted to a do loop that walks up the prototype chain until the property is found or the chain has ended.
