Instance Flow flows instances of one Class Class defines type of zero, one or many Instance Flow

All instance references communicated in an Instance Flow must belong to the same Class. We can say that the Class, and more specifically, the primary Identifier of that Class establishes the type of data that can be transmitted in the Instance Flow.

The same Class may define many Instance Flows, both in the same Activity and across multiple Activities.

Formalization

Instance Flow.(Class, Domain) -> Class.(Name, Domain)
