org.axonframework.saga.Saga
Interface describing an implementation of a Saga. Sagas are instances that handle events and may possibly produce new commands or have other side effects. Typically, Sagas are used to manage long running business transactions.
Multiple instances of a single type of Saga may exist. In that case, each Saga will be managing a different transaction. Sagas need to be associated with concepts in order to receive specific events. These associations are managed through AssociationValues. For example, to associate a saga with an Order with ID 1234, this saga needs an association value with key "orderId" and value "1234". @author Allard Buijze @since 0.7
