Method Detail

get

public short get(int index)
Description copied from interface: Uint8Array
Retrieve one element of this view.

Specified by:
get in interface Uint8Array
Returns:
the requested element, 0-255

length

public int length()
Description copied from interface: Uint8Array
The length in elements of this view.

Specified by:
length in interface Uint8Array
Returns:
non-negative length

set

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: Uint8Array
Set multiple elements in this view from an array, storing starting at the requested offset.

Specified by:
set in interface Uint8Array

set

public void set(short[] 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(short[] array,
                int offset)
Description copied from interface: Uint8Array
Set multiple elements in this view from an array, storing starting at the requested offset.

Specified by:
set in interface Uint8Array

set

public void set(Uint8Array array)
Description copied from interface: Uint8Array
Set multiple elements in this view from another view, storing starting at 0.

Specified by:
set in interface Uint8Array

set

public void set(Uint8Array array,
                int offset)
Description copied from interface: Uint8Array
Set multiple elements in this view from another view, storing starting at the requested offset.

Specified by:
set in interface Uint8Array

subarray

public Uint8Array subarray(int begin)
Description copied from interface: Uint8Array
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.

Specified by:
subarray in interface Uint8Array
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

public Uint8Array subarray(int begin,
                           int end)
Description copied from interface: Uint8Array
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
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
