JavaScript _stream_writable call Examples

Example #1

File: _stream_duplex.js Project: blairzhao111/node-source-detailed

//Duplex stream constructor
function Duplex(options) {
	if(!(this instanceof Duplex)){
		return new Duplex(option);
	}

	//run through both Readable and Writable stream constructor to construct both parts of them in an instance of Duplex.
	Readable.call(this, options);
	Writable.call(this, options);

	if(options && options.readable === false){
		this.readable = false;
	}

	if(options && options.writable === false){
		this.writable = false;
	}

	//by default., Duplex allows half open.
	this.allowHalfOpen = true;
	if(options && options.allowHalfOpen === false){
		this.allowHalfOpen = false;
	}

	//register a once listener on its Readable part's 'end' event. 
	this.once('end', onend);
}

Example #2

File: duplex.js Project: AaronRutledge/first-pouchdb-app

function Duplex(options) {
  if (!(this instanceof Duplex))
    return new Duplex(options);

  Readable.call(this, options);
  Writable.call(this, options);

  this.allowHalfOpen = true;
  if (options && options.allowHalfOpen === false)
    this.allowHalfOpen = false;

  this.once('end', onend);
}

Example #3

File: test-stream-pipe-after-end.js Project: DavidCai1993/node

function TestWritable(opt) {
  if (!(this instanceof TestWritable))
    return new TestWritable(opt);
  Writable.call(this, opt);
  this._written = [];
}
