A templated class that is used to register goog.pubsub.PubSub
subscribers.
Typical usage for a publisher:
/** @type {!goog.pubsub.TopicId<!zorg.State>}
zorg.TopicId.STATE_CHANGE = new goog.pubsub.TopicId(
goog.events.getUniqueId('state-change'));
// Compiler enforces that these types are correct.
pubSub.publish(zorg.TopicId.STATE_CHANGE, zorg.State.STARTED);
Typical usage for a subscriber:
// Compiler enforces the callback parameter type.
pubSub.subscribe(zorg.TopicId.STATE_CHANGE, function(state) {
if (state == zorg.State.STARTED) {
// Handle STARTED state.
}
});
