Description

TBoldSubscription is an abstract superclass. The actual subscriptions are the concrete subclasses of TBoldSubscription. A TBoldSubscription has 4 basic properties, a TBoldPublisher, a TBoldSubscriber, a match condition and a requested event. The requested event allows mapping of one or more actual events an event meaningful for the Subscriber. Each subscription defines the conditions for notifying the subscriber. They will normally be a TBoldEvent or a set of TBoldSmallEvents. When SendEvent is called it checks all the publishers subscriptions. For each subscription that matches the event Receive is called for the corresponding subscriber. The same is done for SendQuery and Answer
