public interface WriteStream<T> extends StreamBase
| Modifier and Type | Method and Description |
|---|---|
WriteStream<T> |
drainHandler(Handler<Void> handler)
Set a drain handler on the stream.
|
void |
end()
Ends the stream.
|
void |
end(Handler<AsyncResult<Void>> handler)
Same as
end() but with an handler called when the operation completes |
void |
end(T data)
Same as
end() but writes some data to the stream before ending. |
void |
end(T data,
Handler<AsyncResult<Void>> handler)
Same as but with an
handler called when the operation completes |
WriteStream<T> |
exceptionHandler(Handler<Throwable> handler)
Set an exception handler on the write stream.

WriteStream<T> |
setWriteQueueMaxSize(int maxSize)
Set the maximum size of the write queue to
maxSize. |
WriteStream<T> |
write(T data)
Write some data to the stream.
|
WriteStream<T> |
write(T data,
Handler<AsyncResult<Void>> handler)
Same as but with an
handler called when the operation completes |
boolean |
writeQueueFull()
This will return
true if there are more bytes in the write queue than the value set using setWriteQueueMaxSize(int) |

Once the stream has ended, it cannot be used any more.

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...maxSize - the max size of the write streamboolean writeQueueFull()

The stream implementation defines when the drain handler, for example it could be when the queue size has been
