Class AssociationValue

java.lang.Object

org.axonframework.eventhandling.saga.AssociationValue

All Implemented Interfaces:

Serializable

public class AssociationValue
extends Object
implements Serializable

A combination of key and value by which a Saga can be found. Sagas are triggered by events that have a property that the saga is associated with. A single Association Value can lead to multiple Sagas, and a single Saga can be associated with multiple Association Values.

Two association values are considered equal when both their key and value are equal. For example, a Saga managing Orders could have a AssociationValue with key "orderId" and the order identifier as value.
