Instance Method Details
- (void) cancel { ... }
This method returns an undefined value.
Stop message consumption from a queue.The operation is asynchronous. When consumption will be stopped, you can by notified via #end_handler

- (self) end_handler { ... }
Set an end handler. Once the stream has canceled successfully, the handler will be called.

- (self) fetch(amount = nil)
Fetch the specified
amount
of elements. If the ReadStream
has been paused, reading will
recommence with the specified amount
of items, otherwise the specified amount
will
be added to the current stream demand.

- (self) handler { ... }
Set a message handler. As message appear in a queue, the handler will be called with the message.

- (self) pause
Pause the stream of incoming messages from queue.
The messages will continue to arrive, but they will be stored in a internal queue. If the queue size would exceed the limit provided by , then incoming messages will be discarded.

- (::Vertx::Pipe) pipe

The stream will be resumed when the pipe will be wired to a
WriteStream
.

- (void) pipe_to(dst = nil) { ... }
This method returns an undefined value.
Pipe thisReadStream
to the WriteStream
.
Elements emitted by this stream will be written to the write stream until this stream ends or fails.
Once this stream has ended or failed, the write stream will be ended and the handler
will be
called with the result.
