{{alias}}( size )
|
|
Returns a shared array buffer having a specified number of bytes.
|
|
|
|
A shared array buffer behaves similarly to a non-shared array buffer, except
|
|
that a shared array buffer allows creating views of memory shared between
|
|
threads.
|
|
|
|
Buffer contents are initialized to 0.
|
|
|
|
If an environment does not support shared array buffers, the function throws
|
|
an error.
|
|
|
|
Parameters
|
|
----------
|
|
size: integer
|
|
Number of bytes.
|
|
|
|
Returns
|
|
-------
|
|
out: SharedArrayBuffer
|
|
A shared array buffer.
|
|
|
|
Examples
|
|
--------
|
|
// Assuming an environment supports SharedArrayBuffers...
|
|
> var buf = new {{alias}}( 5 )
|
|
<SharedArrayBuffer>
|
|
|
|
|
|
{{alias}}.length
|
|
Number of input arguments the constructor accepts.
|
|
|
|
Examples
|
|
--------
|
|
> {{alias}}.length
|
|
1
|
|
|
|
|
|
{{alias}}.prototype.byteLength
|
|
Read-only property which returns the length (in bytes) of the array buffer.
|
|
|
|
Examples
|
|
--------
|
|
// Assuming an environment supports SharedArrayBuffers...
|
|
> var buf = new {{alias}}( 5 );
|
|
> buf.byteLength
|
|
5
|
|
|
|
|
|
{{alias}}.prototype.slice( [start[, end]] )
|
|
Copies the bytes of a shared array buffer to a new shared array buffer.
|
|
|
|
Parameters
|
|
----------
|
|
start: integer (optional)
|
|
Index at which to start copying buffer contents (inclusive). If
|
|
negative, the index is relative to the end of the buffer.
|
|
|
|
end: integer (optional)
|
|
Index at which to stop copying buffer contents (exclusive). If negative,
|
|
the index is relative to the end of the buffer.
|
|
|
|
Returns
|
|
-------
|
|
out: SharedArrayBuffer
|
|
A new shared array buffer whose contents have been copied from the
|
|
calling shared array buffer.
|
|
|
|
Examples
|
|
--------
|
|
// Assuming an environment supports SharedArrayBuffers...
|
|
> var b1 = new {{alias}}( 10 );
|
|
> var b2 = b1.slice( 2, 6 );
|
|
> var bool = ( b1 === b2 )
|
|
false
|
|
> b2.byteLength
|
|
4
