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.
