Class PropertyReadExpander

  • public class PropertyReadExpander
extends com.ibm.wala.cast.tree.rewrite.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.
