All Implemented Interfaces:

public class NativeDataView
extends NativeArrayBufferView

This class represents the JavaScript "DataView" interface, which allows direct manipulations of the bytes in a NativeArrayBuffer. Java programmers would be best off getting the underling "byte[]" array from the NativeArrayBuffer and manipulating it directly, perhaps using the "ByteIo" class as a helper.

Method Details

getClassName

public String getClassName()

Description copied from class: ScriptableObject

Return the name of the class.

This is typically the same name as the constructor. Classes extending ScriptableObject must implement this abstract method.

Specified by:

getClassName in interface Scriptable

Specified by:

getClassName in class ScriptableObject

init

public static void init(Context cx,
 Scriptable scope,
 boolean sealed)

execIdCall

public Object execIdCall(IdFunctionObject f,
 Context cx,
 Scriptable scope,
 Scriptable thisObj,
 Object[] args)

Description copied from class: IdScriptableObject

'thisObj' will be null if invoked as constructor, in which case * instance of Scriptable should be returned.

Specified by:

execIdCall in interface IdFunctionCall

Overrides:

execIdCall in class IdScriptableObject

initPrototypeId

protected void initPrototypeId(int id)

Overrides:

initPrototypeId in class IdScriptableObject

findPrototypeId

protected int findPrototypeId(String s)

Overrides:

findPrototypeId in class IdScriptableObject
