Node.js中的process.nextTick使用实例

var MyConstructor = function() {
 ...
 process.nextTick(function() {
 self._continue();
 });
};
 
MyConstructor.prototype.__proto__ = EventEmitter.prototype;
 
MyConstructor.prototype._continue = function() {
 // without the process.nextTick
 // these events would be emitted immediately
 // with no listeners. they would be lost.
 this.emit('data', 'hello');
 this.emit('data', 'world');
 this.emit('end');
};
 
function(req, res, next) {
 var c = new MyConstructor(...);
 c.on('data', function(data) {
 console.log(data);
 });
 c.on('end', next);
}
