Class JSArrayToDenseObjectArrayNode

java.lang.Object

com.oracle.truffle.api.nodes.Node

com.oracle.truffle.js.nodes.JavaScriptBaseNode

com.oracle.truffle.js.nodes.array.JSArrayToDenseObjectArrayNode

All Implemented Interfaces:

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

public abstract class JSArrayToDenseObjectArrayNode
extends JavaScriptBaseNode

Converts a JS array to an Object[]. If the array is sparse or has holes, it is compacted to a dense array that consists of only actual elements. Used by Array.prototype.sort.
