`void`	`end()` Closes the producer, calls `close()`

`MessageProducer`	`getDelegate()`
`int`	`hashCode()`

`static <T> MessageProducer<T>`	`newInstance(MessageProducer arg, io.vertx.lang.rx.TypeArg<T> __typeArg_T)`
`MessageProducer<T>`	`send(T message)` This method actually sends a message using the send semantic regardless this producer is a sender or a publisher.
`<R> MessageProducer<T>`	`send(T message, Handler<AsyncResult<Message<R>>> replyHandler)` Like `send(T)` but specifying a `replyHandler` that will be called if the recipient subsequently replies to the message.
`MessageProducer<T>`	`setWriteQueueMaxSize(int maxSize)` Set the maximum size of the write queue to `maxSize`.
`String`	`toString()`

  - writeQueueFull
```
public boolean writeQueueFull()
```

    Specified by:
    
    writeQueueFull in interface WriteStream<T>
    
    Returns:
    
    true if write queue is full
  - send
```
public MessageProducer<T> send(T message)
```
    This method actually sends a message using the send semantic regardless this producer is a sender or a publisher.
    
    Parameters:
    
    message - the message to send
    
    Returns:
    
    reference to this for fluency
  - send
```
public <R> MessageProducer<T> send(T message,
                                   Handler<AsyncResult<Message<R>>> replyHandler)
```
    Like send(T) but specifying a replyHandler that will be called if the recipient subsequently replies to the message.
    
    Parameters:
    
    message - the message to send
    
    replyHandler - reply handler will be called when any reply from the recipient is received, may be null
    
    Returns:
    
    reference to this for fluency
  - exceptionHandler
```
public MessageProducer<T> exceptionHandler(Handler<Throwable> handler)
```
    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:
    
    handler - the exception handler
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - write
```
public MessageProducer<T> write(T data)
```
    Description copied from interface: WriteStream
    
    Write some data to the stream. The data is 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 Pump.
    
    Specified by:
    
    write in interface WriteStream<T>
    
    Parameters:
    
    data - the data to write
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - setWriteQueueMaxSize
```
public MessageProducer<T> setWriteQueueMaxSize(int maxSize)
```
    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 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...
    
    Specified by:
    
    setWriteQueueMaxSize in interface WriteStream<T>
    
    Parameters:
    
    maxSize - the max size of the write stream
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - drainHandler
```
public MessageProducer<T> drainHandler(Handler<Void> handler)
```
    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 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.
    
    Specified by:
    
    drainHandler in interface WriteStream<T>
    
    Parameters:
    
    handler - the handler
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - deliveryOptions
```
public MessageProducer<T> deliveryOptions(DeliveryOptions options)
```
    Update the delivery options of this producer.
    
    Parameters:
    
    options - the new options
    
    Returns:
    
    this producer object
  - address
```
public String address()
```
    Returns:
    
    The address to which the producer produces messages.
  - end
```
public void end()
```
    Closes the producer, calls close()
    
    Specified by:
    
    end in interface WriteStream<T>
  - close
```
public void close()
```
    Closes the producer, this method should be called when the message producer is not used anymore.
  - newInstance
```
public static <T> MessageProducer<T> newInstance(MessageProducer arg)
```
  - newInstance
```
public static <T> MessageProducer<T> newInstance(MessageProducer arg,
                                                 io.vertx.lang.rx.TypeArg<T> __typeArg_T)
```
