Class ArrayBufferViewGetByteLengthNode

java.lang.Object

com.oracle.truffle.api.nodes.Node

com.oracle.truffle.js.nodes.JavaScriptBaseNode

com.oracle.truffle.js.nodes.access.ArrayBufferViewGetByteLengthNode

All Implemented Interfaces:

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

public abstract class ArrayBufferViewGetByteLengthNode
extends JavaScriptBaseNode

Optimization over JSArrayBufferView.getByteLength to have a valueProfile on the TypedArray, potentially avoiding a virtual call.
