Module: Vertx::WriteStream
- Includes:
- StreamBase
- Included in:
- AsyncFile, HttpClientRequest, HttpServerResponse, MessageProducer, NetSocket, WebSocketBase, WriteStreamImpl, VertxAmqpClient::AmqpSender, VertxKafkaClient::KafkaProducer, VertxWeb::SockJSSocket
- Defined in:
- /Users/julien/java/vertx-aggregator/modules/vertx-lang-ruby/vertx-lang-ruby/target/classes/vertx/write_stream.rb
Instance Method Summary (collapse)
-
- (self) drain_handler { ... }
Set a drain handler on the stream.
-
- (void) end(data = nil) { ... }
Same as but with an handler called when the operation completes.
-
- (self) exception_handler { ... }
Set an exception handler on the write stream.
-
- (self) set_write_queue_max_size(maxSize = nil)
Set the maximum size of the write queue to maxSize.
-
- (void) write(data = nil) { ... }
Same as but with an handler called when the operation completes.
-
- (true, false) write_queue_full?
This will return true if there are more bytes in the write queue than the value set using #set_write_queue_max_size.
Instance Method Details
- (self) drain_handler { ... }
Set a drain handler on the stream. If the write queue is full, then the handler will be called when the write
queue is ready to accept buffers again. See Pump for an example of this being used.
The stream implementation defines when the drain handler, for example it could be when the queue size has been
reduced to
maxSize / 2.

- (self) set_write_queue_max_size(maxSize = nil)
Set the maximum size of the write queue to
maxSize. You will still be able to write to the stream even
if there is more than maxSize items in the write queue. This is used as an indicator by classes such as
Pump to provide flow control.
The value is defined by the implementation of the stream, e.g in bytes for a
NetSocket, the number of Message for a
MessageProducer, etc...
