Get the underlying ArrayBuffer.

Specified by:

buffer in interface ArrayBufferView

Returns:

the ArrayBuffer instance backing this view

byteLength

public int byteLength()

Description copied from interface: ArrayBufferView

Get the length of this view in bytes.

Specified by:

byteLength in interface ArrayBufferView

public void set(int index,
                int value)

Description copied from interface: Uint8Array

Set one element in this view.

Specified by:

set in interface Uint8Array

set

public void set(int[] array)

Description copied from interface: Uint8Array

Set multiple elements in this view from an array, storing starting at 0.

Specified by:

set in interface Uint8Array

set

public void set(int[] array,
                int offset)

Description copied from interface: Uint8ClampedArray

Create a new view from the same array, from offset to (but not including) end in this view. These indices are clamped to legal indices into this view, so it is not an error to specify invalid indices.

Specified by:

subarray in interface Uint8Array

Specified by:

subarray in interface Uint8ClampedArray

Parameters:

begin - offset into this view if non-negative; if negative, an index from the end of this view

end - offset into this view if non-negative; if negative, an index from the end of this view

Returns:

a new Uint8ClampedArray instance
