{{alias}}( src[, options] )
|
||
|
Creates a readable stream from an 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
|
||
|
----------
|
||
|
src: ArrayLikeObject
|
||
|
Source value.
|
||
|
|
||
|
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".
|
||
|
|
||
|
options.dir: integer (optional)
|
||
|
Iteration direction. If set to `-1`, a stream iterates over elements
|
||
|
from right-to-left. Default: 1.
|
||
|
|
||
|
Returns
|
||
|
-------
|
||
|
stream: ReadableStream
|
||
|
Readable stream.
|
||
|
|
||
|
Examples
|
||
|
--------
|
||
|
> function fcn( chunk ) { console.log( chunk.toString() ); };

|
||
|
> var o = {{alias:@stdlib/streams/node/inspect-sink}}( fcn );
|
||
|
> s.pipe( o );
|
||
|
|
||
|
|
||
|

{{alias}}.objectMode( src[, options] )
|
||
|
Returns an "objectMode" readable stream from an array-like object.
