java.lang.Object

com.oracle.truffle.api.nodes.Node

com.oracle.truffle.js.nodes.JavaScriptBaseNode

com.oracle.truffle.js.nodes.array.JSArrayElementIndexNode

com.oracle.truffle.js.nodes.array.JSArrayLastElementIndexNode

All Implemented Interfaces:

com.oracle.truffle.api.nodes.NodeInterface, Cloneable

public abstract class JSArrayLastElementIndexNode
extends JSArrayElementIndexNode

Provides the functionality of ScriptArray.lastElementIndex but additionally adheres to the prototype chain. It is implemented in a specialized and profiled fashion.
