Method Detail

put

public boolean put(java.lang.String queueName,
                   java.lang.Object message)

Submit a message on given queue without any delay, listener would try to consume this message immediately but due to heavy load message consumption can be delayed if message producer rate is higher than the rate at consumer consume the messages.

Parameters:

queueName - on which queue message has to be send

message - message object it could be any arbitrary object.

Returns:

message was submitted successfully or failed.

put

public boolean put(java.lang.String queueName,
                   java.lang.Object message,
                   int retryCount)

This is an extension to the method put(String, Object). By default container would try to deliver the same message for Integer.MAX_VALUE times, but that can be either overridden using RqueueListener.numRetries(), even that value can be overridden using this method.

Parameters:

queueName - on which queue message has to be send

message - message object it could be any arbitrary object.

retryCount - how many times a message would be retried, before it can be discarded or sent to dead letter queue configured using RqueueListener.delayedQueue()

Returns:

message was submitted successfully or failed.

put

public boolean put(java.lang.String queueName,
                   java.lang.Object message,
                   long delayInMilliSecs)

This is the extension to the method put(String, Object), in this we can specify when this message would be visible to the consumer.

Parameters:

queueName - on which queue message has to be send

message - message object it could be any arbitrary object.

delayInMilliSecs - delay in milli seconds, this message would be only visible to the listener when number of millisecond has elapsed.

Returns:

message was submitted successfully or failed.

getAllMessages

public java.util.List<java.lang.Object> getAllMessages(java.lang.String queueName)

Find all messages stored on a given queue, it considers all the messages including delayed and non-delayed.

Parameters:

queueName - queue name to be query for

Returns:

list of messages

put

public boolean put(java.lang.String queueName,
                   java.lang.Object message,
                   int retryCount,
                   long delayInMilliSecs)

Extension to the put(String, Object, long), as like other retry method we can override number of times a listener would be retrying

Parameters:

queueName - on which queue message has to be send

message - message object it could be any arbitrary object.

retryCount - how many times a message would be retried, before it can be discarded or sent to dead letter queue configured using RqueueListener.delayedQueue()

delayInMilliSecs - delay in milli seconds, this message would be only visible to the listener when number of millisecond has elapsed.

Returns:

message was submitted successfully or failed.
