public interface Uint8Array
extends ArrayBufferView

A view representing an ArrayBuffer as 8-bit unsigned integers. Storing out-of-range values are mapped to valid values by taking the bottom 8 bits of the value as an unassigned. {@link "http://www.khronos.org/registry/typedarray/specs/latest/#7"}

Method Detail

length

int length()

The length in elements of this view.

Returns:

non-negative length

get

short get(int index)

Retrieve one element of this view.

Parameters:

index -

Returns:

the requested element, 0-255

set

void set(int index,
         int value)

Set one element in this view.

Parameters:

index -

value -

set

void set(Uint8Array array)

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

Parameters:

array -

set

void set(Uint8Array array,
         int offset)

Set multiple elements in this view from another view, storing starting at the requested offset.

Parameters:

array -

offset -

set

void set(int[] array)

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

Parameters:

array -

set

void set(int[] array,
         int offset)

Set multiple elements in this view from an array, storing starting at the requested offset.

Parameters:

array -

offset -

set

void set(short[] array)

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

Parameters:

array -

set

void set(short[] array,
         int offset)

Set multiple elements in this view from an array, storing starting at the requested offset.

Parameters:

array -

offset -

subarray

Uint8Array subarray(int begin)

Create a new view from the same array, from offset to the end of this view. These offset is clamped to legal indices into this view, so it is not an error to specify an invalid index.

Parameters:

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

Returns:

a new Uint8Array instance

subarray

Uint8Array subarray(int begin,
                    int end)

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.

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 Uint8Array instance
