flow-ceil
Transform stream factory to round streamed numeric data values toward positive infinity (ceil).
Installation
$ npm install flow-ceil
API
To create a stream factory,
var ceilStream = require( 'flow-ceil' );
// Create a new factory:
var cStream = ceilStream();
cStream.stream()
To create a new stream to round streamed numeric values toward positive infinity,
var stream = cStream.stream();
Usage
Methods are chainable.
ceilStream()
.stream()
.pipe( /* writable stream */ );
Examples
var eventStream = require( 'event-stream' ),
cStream = require( 'flow-ceil' );
// Create some data...
var data = new Array( 1000 );
for ( var i = 0; i < data.length; i++ ) {
data[ i ] = Math.random()-0.5;
}
// Create a readable stream:
var readStream = eventStream.readArray( data );
// Create a new stream:
var stream = cStream().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,
$ 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.
