Transform stream factory to round streamed numeric data values.
npm install flow-roundflow-round
==========
Transform stream factory to round streamed numeric data values.
`` bash`
$ npm install flow-round
To create a stream factory,
` javascript
var roundStream = require( 'flow-round' );
// Create a new factory:
var rStream = roundStream();
`
To create a new stream to round streamed numeric values,
` javascript`
var stream = rStream.stream();
Methods are chainable.
` javascript`
roundStream()
.stream()
.pipe( / writable stream / );
` javascript
var eventStream = require( 'event-stream' ),
rStream = require( 'flow-round' );
// Create some data...
var data = new Array( 1000 );
for ( var i = 0; i < data.length; i++ ) {
data[ i ] = Math.random()*10;
}
// Create a readable stream:
var readStream = eventStream.readArray( data );
// Create a new stream:
var stream = rStream().stream();
// Pipe the data:
readStream.pipe( stream )
.pipe( eventStream.map( function( d, clbk ) {
clbk( null, d.toString()+'\n' );
}))
.pipe( process.stdout );
`
To run the example code from the top-level application directory,
` bash`
$ node ./examples/index.js
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:
` bash``
$ mocha
All new feature development should have corresponding unit tests to validate correct functionality.
