Public Functions Documentation

function ~MamaBasicWildCardSubscription

virtual ~MamaBasicWildCardSubscription()

The destructor will call [destroy()](classWombat_1_1MamaBasicSubscription.html#function-destroy) if the subscription has not already been destroyed.

function MamaBasicWildCardSubscription

MamaBasicWildCardSubscription(
    void 
)

Constructor. Call createBasicWildCard() to activate the subscription.

function create

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

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.

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.

function getSymbol

virtual const char * getSymbol(
    void 
) const

Return: The topic.

Return the symbol for this subscription.

function getSource

virtual const char * getSource(
    void 
) const

Return: The topic.

Return the source for this subscription.

function getTopicClosure

virtual void * getTopicClosure() const

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.

function setTopicClosure

virtual void setTopicClosure(
    void * closure
)

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

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

@prarm closure The closure.

function muteCurrentTopic

virtual void muteCurrentTopic(
    void 
)

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

function getBasicWildCardCallback

virtual MamaBasicWildCardSubscriptionCallback * getBasicWildCardCallback(
    void 
) const

Return: the callback.

Return the [MamaSubscriptionCallback](classWombat_1_1MamaSubscriptionCallback.html) for this subscription.
