virtual void Wombat::MamaBasicWildCardSubscription::create ( MamaTransport *  transport, MamaQueue *  queue, MamaBasicWildCardSubscriptionCallback *  callback, const char *  source, const char *  topic, void *  closure = NULL  )

virtual

Create a basic wild card subscription without market data semantics.

If the topic is NULL for WMW, this method creates a "transport" subscription that subscribes to all the topics from publishers with the the "publish_name" property equal to the source value.

Parameters

transport	The transport to use. Must be a basic transport.
queue	The queue.
callback	The mamaMsgCallbacks structure containing the three callback methods.
topic	The topic.
closure	The caller supplied closure.

virtual const char* Wombat::MamaBasicWildCardSubscription::getSymbol ( void  ) const

virtual

Return the symbol for this subscription.

Returns

The topic.

virtual const char* Wombat::MamaBasicWildCardSubscription::getSource ( void  ) const

virtual

Return the source for this subscription.

Returns

The topic.

virtual void* Wombat::MamaBasicWildCardSubscription::getTopicClosure ( ) const

virtual

Get the closure for the specific wildcard topic.

This method may only be called from the onMsg callback.

@ return The closure specified by ::setTopicClosure() or NULL if no topic closure set.

virtual void Wombat::MamaBasicWildCardSubscription::setTopicClosure ( void *  closure)

virtual

Set the topic closure for the current message's topic.

This method can only be invoked from the onMsg() callback.

closure The closure.

virtual void Wombat::MamaBasicWildCardSubscription::muteCurrentTopic ( void  )

virtual

For "transport" subscriptions (WMW only) stop processing messages for the current topic.

virtual MamaBasicWildCardSubscriptionCallback* Wombat::MamaBasicWildCardSubscription::getBasicWildCardCallback ( void  ) const

virtual

Return the MamaSubscriptionCallback for this subscription.

Returns

the callback.
