Constructor & Destructor Documentation

activemq::core::ActiveMQConsumer::ActiveMQConsumer ( const Pointer< activemq::core::kernels::ActiveMQConsumerKernel > & kernel )

Create a new ActiveMQConsumer that contains the pointer to the Kernel that implement the real MessageConsumer functionality.

Parameters

ActiveMQConsumerKernel This Consumer's functionality kernel.

virtual activemq::core::ActiveMQConsumer::~ActiveMQConsumer ( )

virtual

Member Function Documentation

virtual void activemq::core::ActiveMQConsumer::close ( )

virtual

Closes this object and deallocates the appropriate resources.

The object is generally no longer usable after calling close.

Exceptions

CMSException - If an error occurs while the resource is being closed.

Implements cms::Closeable.

const Pointer<commands::ConsumerId>& activemq::core::ActiveMQConsumer::getConsumerId ( ) const

Get the Consumer Id for this consumer.

Returns: Reference to a Consumer Id Object

const Pointer<commands::ConsumerInfo>& activemq::core::ActiveMQConsumer::getConsumerInfo ( ) const

Get the Consumer information for this consumer.

Returns: Reference to a Consumer Info Object

decaf::lang::Exception* activemq::core::ActiveMQConsumer::getFailureError ( ) const

Gets the error that caused this Consumer to be in a Failed state, or NULL if there is no Error.

Returns: pointer to the error that faulted this Consumer or NULL.

int activemq::core::ActiveMQConsumer::getMessageAvailableCount ( ) const

Returns: the number of Message's this consumer is waiting to Dispatch.

virtual cms::MessageAvailableListener* activemq::core::ActiveMQConsumer::getMessageAvailableListener ( ) const

virtual

Gets the MessageAvailableListener that this class will send mew Message notification events to.

Returns: The listener of message events received by this consumer.

Exceptions

CMSException - If an internal error occurs.

Implements cms::MessageConsumer.

virtual cms::MessageListener* activemq::core::ActiveMQConsumer::getMessageListener ( ) const

virtual

Gets the MessageListener that this class will send mew Message notification events to.

Returns: The listener of messages received by this consumer

Exceptions

CMSException - If an internal error occurs.

Implements cms::MessageConsumer.

virtual std::string activemq::core::ActiveMQConsumer::getMessageSelector ( ) const

virtual

Gets this message consumer's message selector expression.

Returns: This Consumer's selector expression or "".

Exceptions

CMSException - If an internal error occurs.

Implements cms::MessageConsumer.

virtual cms::MessageTransformer* activemq::core::ActiveMQConsumer::getMessageTransformer ( ) const

virtual

Gets the currently configured MessageTransformer for this MessageConsumer.

Returns: the pointer to the currently set cms::MessageTransformer.

Implements cms::MessageConsumer.

RedeliveryPolicy* activemq::core::ActiveMQConsumer::getRedeliveryPolicy ( ) const

Gets a pointer to this Consumer's Redelivery Policy object, the Consumer retains ownership of this pointer so the caller should not delete it.

Returns: a Pointer to a RedeliveryPolicy that is in use by this Consumer.

bool activemq::core::ActiveMQConsumer::isClosed ( ) const

Returns: if this Consumer has been closed.

virtual cms::Message* activemq::core::ActiveMQConsumer::receive ( )

virtual

Synchronously Receive a Message.

Returns: new message which the caller owns and must delete.

Exceptions

CMSException - If an internal error occurs.

Implements cms::MessageConsumer.

virtual cms::Message* activemq::core::ActiveMQConsumer::receive ( int millisecs )

virtual

Synchronously Receive a Message, time out after defined interval.

Returns null if nothing read.

Returns: new message which the caller owns and must delete.

Exceptions

CMSException - If an internal error occurs.

Implements cms::MessageConsumer.

virtual cms::Message* activemq::core::ActiveMQConsumer::receiveNoWait ( )

virtual

Receive a Message, does not wait if there isn't a new message to read, returns NULL if nothing read.

Returns: new message which the caller owns and must delete.

Exceptions

CMSException - If an internal error occurs.

Implements cms::MessageConsumer.

virtual void activemq::core::ActiveMQConsumer::setMessageAvailableListener ( cms::MessageAvailableListener * listener )

virtual

Sets the MessageAvailableListener that this class will send events to if the consumer is in synchronous consumption mode and a new Message has arrived.

Parameters

listener The listener of new message events fired by this consumer.

Exceptions

CMSException - If an internal error occurs.

Implements cms::MessageConsumer.

virtual void activemq::core::ActiveMQConsumer::setMessageListener ( cms::MessageListener * listener )

virtual

Sets the MessageListener that this class will send notifs on.

Parameters

listener The listener of messages received by this consumer.

Exceptions

CMSException - If an internal error occurs.

Implements cms::MessageConsumer.

virtual void activemq::core::ActiveMQConsumer::setMessageTransformer ( cms::MessageTransformer * transformer )

virtual

Set an MessageTransformer instance that is applied to all cms::Message objects before they are dispatched to client code.

The CMS code never takes ownership of the MessageTransformer pointer which implies that the client code must ensure that the object remains valid for the lifetime of the CMS object to which the MessageTransformer has been assigned.

Parameters

transformer Pointer to the cms::MessageTransformer to apply on each cms:;Message dispatch.

Implements cms::MessageConsumer.

void activemq::core::ActiveMQConsumer::setRedeliveryPolicy ( RedeliveryPolicy * policy )

Sets the RedeliveryPolicy this Consumer should use when a rollback is performed on a transacted Consumer.

The Consumer takes ownership of the passed pointer. The Consumer's redelivery policy can never be null, a call to this method with a NULL pointer is ignored.

Parameters

policy Pointer to a Redelivery Policy object that his Consumer will use.

virtual void activemq::core::ActiveMQConsumer::start ( )

virtual

Starts the service.

Exceptions

CMSException if an internal error occurs while starting.

Implements cms::Startable.

virtual void activemq::core::ActiveMQConsumer::stop ( )

virtual

Stops this service.

Exceptions

CMSException - if an internal error occurs while stopping the Service.

Implements cms::Stoppable.
