Class JSToObjectArrayNode

java.lang.Object

com.oracle.truffle.api.nodes.Node

com.oracle.truffle.js.nodes.JavaScriptBaseNode

com.oracle.truffle.js.nodes.cast.JSToObjectArrayNode

All Implemented Interfaces:

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

public abstract class JSToObjectArrayNode
extends JavaScriptBaseNode

Converts an arbitrary array-like object to an Object[], with an optional array length limit.

By default, throws TypeError for null and undefined (can be changed by using create(boolean)). Throws a RangeError if the array length exceeds the optional array length limit or the maximum Java array size.
