    • exceptionHandler

      public WriteStream<T> exceptionHandler(Handler<Throwable> hndlr)
      Deprecated.
      Description copied from interface: WriteStream
      Set an exception handler on the write stream.
      Specified by:
      exceptionHandler in interface StreamBase
      Specified by:
      exceptionHandler in interface WriteStream<T>
      Parameters:
      hndlr - the exception handler
      Returns:
      a reference to this, so the API can be used fluently

    • write

      public Future<Void> write(T data)
      Deprecated.
      Description copied from interface: WriteStream
      Write some data to the stream.

      The data is usually put on an internal write queue, and the write actually happens asynchronously. To avoid running out of memory by putting too much on the write queue, check the WriteStream.writeQueueFull() method before writing. This is done automatically if using a Pipe.

      When the data is moved from the queue to the actual medium, the returned Future will be completed with the write result, e.g the future is succeeded when a server HTTP response buffer is written to the socket and failed if the remote client has closed the socket while the data was still pending for write.

      Specified by:
      write in interface WriteStream<T>
      Parameters:
      data - the data to write
      Returns:
      a future completed with the write result

    • end

      public Future<Void> end()
      Deprecated.
      Description copied from interface: WriteStream
      Ends the stream.

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

      Specified by:
      end in interface WriteStream<T>
      Returns:
      a future completed with the result

    • setWriteQueueMaxSize

      public WriteStream<T> setWriteQueueMaxSize(int i)
      Deprecated.
      Description copied from interface: WriteStream
      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 Pipe to provide flow control.

      The value is defined by the implementation of the stream, e.g in bytes for a NetSocket, etc...

      Specified by:
      setWriteQueueMaxSize in interface WriteStream<T>
      Parameters:
      i - the max size of the write stream
      Returns:
      a reference to this, so the API can be used fluently

    • writeQueueFull

      public boolean writeQueueFull()
      Deprecated.
      Description copied from interface: WriteStream
      This will return true if there are more bytes in the write queue than the value set using WriteStream.setWriteQueueMaxSize(int)
      Specified by:
      writeQueueFull in interface WriteStream<T>
      Returns:
      true if write queue is full

    • drainHandler

      public WriteStream<T> drainHandler(Handler<Void> hndlr)
      Deprecated.
      Description copied from interface: WriteStream
      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 Pipe 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.

      Specified by:
      drainHandler in interface WriteStream<T>
      Parameters:
      hndlr - the handler
      Returns:
      a reference to this, so the API can be used fluently

    • streamObserver

      public StreamObserver<T> streamObserver()
      Deprecated.
      Low level control of the observer for advanced use cases.
