{{alias}}( N, buffer, stride, offset[, options] )
|
|
Creates a readable stream from a strided array-like object.
|
|
|
|
In object mode, `null` is a reserved value. If an array contains `null`
|
|
values (e.g., as a means to encode missing values), the stream will
|
|
prematurely end. Consider an alternative encoding or filter `null` values
|
|
prior to invocation.
|
|
|
|
In binary mode, if an array contains `undefined` values, the stream will
|
|
emit an error. Consider providing a custom serialization function or
|
|
filtering `undefined` values prior to invocation.
|
|
|
|
If a serialization function fails to return a string or Buffer, the stream
|
|
emits an error.
|
|
|
|
Parameters
|
|
----------
|
|
N: integer
|
|
Number of values to stream.
|
|
|
|
buffer: ArrayLikeObject
|
|
Array-like object from which to create the stream.
|
|
|
|
stride: integer
|
|
Stride length.
|
|
|
|
offset: integer
|
|
Starting index.
|
|
|
|
options: Object (optional)
|
|
Options.
|
|
|
|
options.objectMode: boolean (optional)
|
|
Specifies whether a stream should operate in "objectMode". Default:
|
|
false.
|
|
|
|
options.encoding: string|null (optional)
|
|
Specifies how Buffer objects should be decoded to strings. Default:
|
|
null.
|
|
|
|
options.highWaterMark: integer (optional)
|
|
Specifies the maximum number of bytes to store in an internal buffer
|
|
before pausing the stream.
|
|
|
|
options.sep: string (optional)
|
|
Separator used to join streamed data. This option is only applicable
|
|
when a stream is not in "objectMode". Default: '\n'.
|
|
|
|
options.serialize: Function (optional)
|
|
Serialization function. The default behavior is to serialize streamed
|
|
values as JSON strings. This option is only applicable when a stream is
|
|
not in "objectMode".
|
|
|
|
Returns
|
|
-------
|
|
stream: ReadableStream
|
|
Readable stream.
|
|
|
|
Examples
|
|
--------
|
|
> function fcn( chunk ) { console.log( chunk.toString() ); };
|
|
> var s = {{alias}}( 3, [ 1, 2, 3 ], 1, 0 );
|
|
> var o = {{alias:@stdlib/streams/node/inspect-sink}}( fcn );
|
|
> s.pipe( o );
|
|
|
|
|
|
{{alias}}.factory( [options] )
|
|
Returns a function for creating readable streams from array-like objects.
|

|
Separator used to join streamed data. This option is only applicable
|
|
when a stream is not in "objectMode". Default: '\n'.
|
|
|
|
options.serialize: Function (optional)
|
|
Serialization function. The default behavior is to serialize streamed
|
|
values as JSON strings. This option is only applicable when a stream is

fcn: Function
|
|
Function for creating readable streams.
|
|
|
|
Examples
|
|
--------
|
|
> var opts = { 'objectMode': true, 'highWaterMark': 64 };
|
|
> var createStream = {{alias}}.factory( opts );
|
|
|
|
|
|
{{alias}}.objectMode( N, buffer, stride, offset[, options] )
|
|
Returns an "objectMode" readable stream from a strided array-like object.
|

|
In object mode, `null` is a reserved value. If an array contains `null`
|
|
values (e.g., as a means to encode missing values), the stream will
|
|
prematurely end. Consider an alternative encoding or filter `null` values
|
