function onCreate

virtual void onCreate(
    MamaBasicWildCardSubscription * subscription
) =0

Parameters:

• subscription The subscription.

Method invoked when subscription creation is complete, and before any calls to onMsg. Since subscriptions are created asynchronous by throttle, this callback provides the subscription instance after the throttle processes the creation request.

    const MamaStatus & status,

) =0

Parameters:

• subscription The subscription.
• status The wombat error code.
• topic The topic for NOT_ENTITLED

Invoked if an error occurs during prior to subscription creation or if the subscription receives a message for an unentitled topic.

If the status is MamaMsgStatus.NOT_ENTITTLED the topic parameter is the specific unentitled topic. If the subscription topic contains wildcards, the subscription may still receive messages for other entitled topics.

    MamaBasicWildCardSubscription * subscription,
    void * closure

Parameters:

• subscription The The Mama Basic Wildcard Subscription.
