Class NativeArrayBufferView

java.lang.Object

org.htmlunit.corejs.javascript.SlotMapOwner

org.htmlunit.corejs.javascript.ScriptableObject

org.htmlunit.corejs.javascript.typedarrays.NativeArrayBufferView

All Implemented Interfaces:

Serializable, ConstProperties, DebuggableObject, Scriptable, SymbolScriptable

Direct Known Subclasses:

NativeDataView, NativeTypedArrayView

public abstract class NativeArrayBufferView
extends ScriptableObject

This class is the abstract parent for all views of the array. It shows a view of the underlying NativeArrayBuffer. Many views may simultaneously share the same buffer, and changes to one will affect all.
