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. Note that this node assumes that the array has only fast own elements and no prototype elements. Used by Array.prototype.sort.
