package org.axonframework.eventsourcing;

The CachingGenericEventSourcingRepository is a special EventSourcingRepository implementation that can act as a repository for any type of EventSourcedAggregateRoot. In contrast to the GenericEventSourcingRepository, it also supports caching.

There is however, a convention that these EventSourcedAggregateRoot classes must adhere to. The type must declare an accessible constructor accepting a org.axonframework.domain.AggregateIdentifier as single parameter. This constructor may not perform any initialization on the aggregate, other than setting the identifier.

If the constructor is not accessible (not public), and the JVM's security setting allow it, the GenericEventSourcingRepository will try to make it accessible.

Parameters:
<T> The aggregate type this repository serves

        extends CachingEventSourcingRepository<T> {

    
Creates a GenericEventSourcingRepository for aggregates of the given aggregateType, using the default locking strategy (optimistic locking). The given type must at least provide an accessible constructor taking a UUID as single parameter.

If the constructor is not accessible, the GenericEventSourcingRepository will attempt to make it so. If JVM security restrictions don't allow that, an exception is thrown.

Parameters:
aggregateType The type of aggregate this repository holds
Throws:
IncompatibleAggregateException If there is no accessible constructor accepting a UUID as single parameter
    public CachingGenericEventSourcingRepository(Class<T> aggregateType) {
        super(new GenericAggregateFactory<T>(aggregateType));
    }
