public class NativeUint8ClampedArray
extends NativeTypedArrayView<java.lang.Integer>

An array view that stores 8-bit quantities and implements the JavaScript "Uint8ClampedArray" interface. It also implements List<Integer> for direct manipulation in Java. Bytes inserted that fall out of the range (0 <= X < 256) will be adjusted so that they match before insertion.

Method Detail

getClassName

public java.lang.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)

construct

protected NativeUint8ClampedArray construct(NativeArrayBuffer ab,
                                            int off,
                                            int len)

Specified by:

construct in class NativeTypedArrayView<java.lang.Integer>

getBytesPerElement

public int getBytesPerElement()

Description copied from class: NativeTypedArrayView

Return the number of bytes represented by each element in the array. This can be useful when wishing to manipulate the byte array directly from Java.

Specified by:

getBytesPerElement in class NativeTypedArrayView<java.lang.Integer>

realThis

protected NativeUint8ClampedArray realThis(Scriptable thisObj,
                                           IdFunctionObject f)

Specified by:

realThis in class NativeTypedArrayView<java.lang.Integer>

js_get

protected java.lang.Object js_get(int index)

Specified by:

js_get in class NativeTypedArrayView<java.lang.Integer>

js_set

protected java.lang.Object js_set(int index,
                                  java.lang.Object c)

Specified by:

js_set in class NativeTypedArrayView<java.lang.Integer>

get

public java.lang.Integer get(int i)

set

public java.lang.Integer set(int i,
                             java.lang.Integer aByte)
