Method Detail

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

getDelegate

public RabbitMQConsumer getDelegate()

Specified by:

getDelegate in interface ReadStream<RabbitMQMessage>

Specified by:

getDelegate in interface StreamBase

toObservable

public Observable<RabbitMQMessage> toObservable()

Specified by:

toObservable in interface ReadStream<RabbitMQMessage>

pipe

public Pipe<RabbitMQMessage> pipe()

Pause this stream and return a to transfer the elements of this stream to a destination .

The stream will be resumed when the pipe will be wired to a WriteStream.

Specified by:

pipe in interface ReadStream<RabbitMQMessage>

Returns:

a pipe

pipeTo

public void pipeTo(WriteStream<RabbitMQMessage> dst,
                   Handler<AsyncResult<Void>> handler)

Pipe this ReadStream to the WriteStream.

Elements emitted by this stream will be written to the write stream until this stream ends or fails.

Once this stream has ended or failed, the write stream will be ended and the handler will be called with the result.

Specified by:

pipeTo in interface ReadStream<RabbitMQMessage>

Parameters:

dst - the destination write stream

handler -

pipeTo

public void pipeTo(WriteStream<RabbitMQMessage> dst)

Pipe this ReadStream to the WriteStream.

Elements emitted by this stream will be written to the write stream until this stream ends or fails.

Once this stream has ended or failed, the write stream will be ended and the handler will be called with the result.

Specified by:

pipeTo in interface ReadStream<RabbitMQMessage>

Parameters:

dst - the destination write stream

rxPipeTo

public Single<Void> rxPipeTo(WriteStream<RabbitMQMessage> dst)

Pipe this ReadStream to the WriteStream.

Elements emitted by this stream will be written to the write stream until this stream ends or fails.

Once this stream has ended or failed, the write stream will be ended and the handler will be called with the result.

Specified by:

rxPipeTo in interface ReadStream<RabbitMQMessage>

Parameters:

dst - the destination write stream

Returns:

exceptionHandler

public RabbitMQConsumer exceptionHandler(Handler<Throwable> exceptionHandler)

Set an exception handler on the read stream.

Specified by:

exceptionHandler in interface ReadStream<RabbitMQMessage>

Specified by:

exceptionHandler in interface StreamBase

Parameters:

exceptionHandler - the exception handler

Returns:

a reference to this, so the API can be used fluently

handler

public RabbitMQConsumer handler(Handler<RabbitMQMessage> messageArrived)

Set a message handler. As message appear in a queue, the handler will be called with the message.

Specified by:

handler in interface ReadStream<RabbitMQMessage>

Parameters:

messageArrived -

Returns:

a reference to this, so the API can be used fluently

pause

public RabbitMQConsumer pause()

Pause the stream of incoming messages from queue.

The messages will continue to arrive, but they will be stored in a internal queue. If the queue size would exceed the limit provided by , then incoming messages will be discarded.

Specified by:

pause in interface ReadStream<RabbitMQMessage>

Returns:

a reference to this, so the API can be used fluently

resume

public RabbitMQConsumer resume()

Resume reading from a queue. Flushes internal queue.

Specified by:

resume in interface ReadStream<RabbitMQMessage>

Returns:

a reference to this, so the API can be used fluently

endHandler

public RabbitMQConsumer endHandler(Handler<Void> endHandler)

Set an end handler. Once the stream has canceled successfully, the handler will be called.

Specified by:

endHandler in interface ReadStream<RabbitMQMessage>

Parameters:

endHandler -

Returns:

a reference to this, so the API can be used fluently

queueName

public String queueName()

Returns:

the name of the queue

setQueueName

public RabbitMQConsumer setQueueName(String name)

Set the name of the queue. This method is typically only required during a connectionEstablishedCallback when the queue name has changed.

Parameters:

name - the name of the queue

Returns:

a reference to this, so the API can be used fluently

consumerTag

public String consumerTag()

Returns:

a consumer tag

cancel

public void cancel(Handler<AsyncResult<Void>> cancelResult)

Stop message consumption from a queue.

The operation is asynchronous. When consumption is stopped, you can also be notified via endHandler(io.vertx.core.Handler<java.lang.Void>)

Parameters:

cancelResult - contains information about operation status: success/fail.

cancel

public void cancel()

Stop message consumption from a queue.

The operation is asynchronous. When consumption is stopped, you can also be notified via endHandler(io.vertx.core.Handler<java.lang.Void>)

rxCancel

public Single<Void> rxCancel()

Stop message consumption from a queue.

The operation is asynchronous. When consumption is stopped, you can also be notified via endHandler(io.vertx.core.Handler<java.lang.Void>)

Returns:

isCancelled

public boolean isCancelled()

Return true if cancel() has been called.

Returns:

true if cancel() has been called.

isPaused

public boolean isPaused()

Returns:

is the stream paused?

fetch

public RabbitMQConsumer fetch(long amount)

Fetch the specified amount of elements. If the ReadStream has been paused, reading will recommence with the specified amount of items, otherwise the specified amount will be added to the current stream demand.

Specified by:

fetch in interface ReadStream<RabbitMQMessage>

Parameters:

amount -

Returns:

a reference to this, so the API can be used fluently
