inlinestatic

Creates a listener for receiving indexed events (with instantiation by event type E and verification)

auto listener = IndexedTxModelListener<Order>::create([](const auto & orderSource, const auto &events, bool
isSnapshot) { if (isSnapshot) { std::cout << "Snapshot:" << std::endl; } else { std::cout << "Update:" <<
std::endl;
    }
 
    for (const auto &e : events) {
        std::cout << "[" << e->getEventFlagsMask().toString() << "]:" << e << std::endl;
    }
 
    std::cout << std::endl;
});
 
builder->withListener(listener);

Template Parameters

E	The event type.

Parameters

onEventsReceived

A functional object, lambda, or function to which indexed event data will be passed.

Returns

A smart pointer to the listener.
