The name for an event used for subscribing to Contract events.

string - An event by name. The event must be non-ambiguous. The parameters will be dereferenced when passed into the listener.

[[ContractEvent]] - A filter from the contract.filters, which will pass only the EventPayload as a single parameter, which includes a .signature property that can be used to further filter the event.

[[TopicFilter]] - A filter defined using the standard Ethereum API which provides the specific topic hash or topic hashes to watch for along with any additional values to filter by. This will only pass a single parameter to the listener, the EventPayload which will include additional details to refine by, such as the event name and signature.

[[DeferredTopicFilter]] - A filter created by calling a [[ContractEvent]] with parameters, which will create a filter for a specific event signature and dereference each parameter when calling the listener.
