flow-multiply
Transform stream factory to perform scalar multiplication on streamed numeric data values.
Installation
$ npm install flow-multiply
API
To create a stream factory,
var multStream = ;// Create a new factory:var mStream = ;
mStream.scalar( [value] )
This method is a setter/getter. If no value
is provided, returns the multiplication factor
(a.k.a. the scalar
); default is 1
. To set the scalar
,
mStream;
mStream.stream()
To create a new scalar multiplication stream,
var stream = mStream;
Usage
Methods are chainable.
;
Examples
var eventStream =mStream = ;// Create some data...var data = 1000 ;for var i = 0; i < datalength; i++data i = Math;// Create a readable stream:var readStream = eventStream;// Create a new scalar multiplication stream:var stream =;// Pipe the data:readStream;
To run the example code from the top-level application directory,
$ node ./examples/index.js
Tests
Unit tests use the Mocha test framework with Chai assertions.
Assuming you have installed Mocha, execute the following command in the top-level application directory to run the tests:
$ mocha
All new feature development should have corresponding unit tests to validate correct functionality.
