public interface WriteStream<T> extends StreamBase
Any class that implements this interface can be used by a Pipe
to pipe data from a ReadStream
to it.
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 |
default void |
end(T data)
Same as
end() but writes some data to the stream before ending. |
default void |
end(T data,
Handler<AsyncResult<Void>> handler)
Same as
#end(T) 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
#write(T) 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) |

method before writing. This is done automatically if using a Pump

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

true
if there are more bytes in the write queue than the value set using setWriteQueueMaxSize(int)
WriteStream<T> drainHandler(Handler<Void> handler)
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
