#through

[![build status](https://secure.travis-ci.org/dominictarr/through.png)](http://travis-ci.org/dominictarr/through)

Easy way to create a `Stream` that is both `readable` and `writable`. Pass in optional `write` and `end` methods. `through` takes care of pause/resume logic.
Use `this.pause()` and `this.resume()` to manage flow.
Check `this.paused` to see current flow state. (write always returns `!this.paused`)

this function is the basis for most of the syncronous streams in [event-stream](http://github.com/dominictarr/event-stream).

``` js
var through = require('through')

through(function write(data) {
    this.emit('data', data)
    //this.pause() 
  },
  function end () { //optional
    this.emit('end')
  })

```
