Hey,
I have a readable Stream which wraps a socket:
function SocketWrapper(socket, options) {
this.socket = socket;
this.socket.on('readable', function() {
self.read();
});
this.socket.on('end', function() {
self.push(null);
});
stream.Readable.call(this, options);
}
util.inherits(SocketWrapper, stream.Readable);
SocketWrapper.prototype._read = function(size) {
var chunk = this.socket.read();
if (chunk === null)
return this.push('');
this.push(chunk);
};
I would now like to read data from the SocketWrapper:
var swrapper = new SocketWrapper(socket);
swrapper.on('readable', function() {
console.log('data', swrapper.read());
});
Unfortunately I always get logged null and never a buffer.
I also logged the whole swrapper object to check out how _readableState
looks like
and the buffer really gets cleared on the readable method but the read
method itself does not return anything.
What did I forget?
