close()
Close the stream
|
ReactiveWriteStream<T> |
drainHandler(Handler<Void> handler)
Set a drain handler on the stream.

Calls
close(). |
ReactiveWriteStream<T> |
exceptionHandler(Handler<Throwable> handler)
Set an exception handler on the write stream.
|
ReactiveWriteStream<T> |
setWriteQueueMaxSize(int maxSize)
Set the maximum size of the write queue to
maxSize. |
ReactiveWriteStream<T> |
write(T data)
Write some data to the stream.
|
ReactiveWriteStream<T> |
write(T data,
Handler<AsyncResult<Void>> handler)
Same as
#write(T) but with an handler called when the operation completes |

WriteStreammaxSize. 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...setWriteQueueMaxSize in interface WriteStream<T>maxSize - the max size of the write streamReactiveWriteStream<T> drainHandler(Handler<Void> handler)

The stream implementation defines when the drain handler, for example it could be when the queue size has been
reduced to maxSize / 2.drainHandler in interface WriteStream<T>handler - the handlervoid end()
