Member Function Documentation

virtual void activemq::cmsutil::CachedConsumer::close ( )

inlinevirtual

Does nothing - the real producer resource will be closed by the lifecycle manager.

Implements cms::Closeable.

virtual cms::MessageAvailableListener* activemq::cmsutil::CachedConsumer::getMessageAvailableListener ( ) const

inlinevirtual

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.

References cms::MessageConsumer::getMessageAvailableListener().

virtual cms::MessageListener* activemq::cmsutil::CachedConsumer::getMessageListener ( ) const

inlinevirtual

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.

References cms::MessageConsumer::getMessageListener().

virtual std::string activemq::cmsutil::CachedConsumer::getMessageSelector ( ) const

inlinevirtual

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.

References cms::MessageConsumer::getMessageSelector().

virtual cms::MessageTransformer* activemq::cmsutil::CachedConsumer::getMessageTransformer ( ) const

inlinevirtual

Gets the currently configured MessageTransformer for this MessageConsumer.

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

Implements cms::MessageConsumer.

References cms::MessageConsumer::getMessageTransformer().

virtual cms::Message* activemq::cmsutil::CachedConsumer::receive ( )

inlinevirtual

Synchronously Receive a Message.

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

Exceptions

CMSException - If an internal error occurs.

Implements cms::MessageConsumer.

References cms::MessageConsumer::receive().

virtual cms::Message* activemq::cmsutil::CachedConsumer::receive ( int millisecs )

inlinevirtual

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.

References cms::MessageConsumer::receive().

virtual cms::Message* activemq::cmsutil::CachedConsumer::receiveNoWait ( )

inlinevirtual

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.

References cms::MessageConsumer::receiveNoWait().

virtual void activemq::cmsutil::CachedConsumer::setMessageAvailableListener ( cms::MessageAvailableListener * listener )

inlinevirtual

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.

References cms::MessageConsumer::setMessageAvailableListener().

virtual void activemq::cmsutil::CachedConsumer::setMessageListener ( cms::MessageListener * listener )

inlinevirtual

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.

References cms::MessageConsumer::setMessageListener().

virtual void activemq::cmsutil::CachedConsumer::setMessageTransformer ( cms::MessageTransformer * transformer )

inlinevirtual

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.

References cms::MessageConsumer::setMessageTransformer().

virtual void activemq::cmsutil::CachedConsumer::start ( )

inlinevirtual

Starts the service.

Exceptions

CMSException if an internal error occurs while starting.

Implements cms::Startable.

References cms::Startable::start().

virtual void activemq::cmsutil::CachedConsumer::stop ( )
