Nested Class Summary

Nested Classes

Modifier and Type	Interface	Description
static class	StatefulAggregateInstanceFactory.ObjenesisAggregateInstanceFactory	StatefulAggregateInstanceFactory that uses Objenesis to create a new instance of the Aggregate Please note: Objenesis doesn't initialize fields nor call any constructors, so you Aggregate design needs to take this into consideration. All concrete aggregates that extends AggregateRoot have been prepared to be initialized by Objenesis
static class	StatefulAggregateInstanceFactory.ReflectionBasedAggregateInstanceFactory	StatefulAggregateInstanceFactory that calls the default no-arguments constructor on the concrete Aggregate type to create a new instance of the Aggregate

Method Details

create

<ID,
AGGREGATE> AGGREGATE create(ID id,
 Class<AGGREGATE> aggregateType)

Create an instance of the Aggregate

Type Parameters:

ID - the type of aggregate id

AGGREGATE - the Aggregate implementation type

Parameters:

id - the id value

aggregateType - the Aggregate implementation type

Returns:

new aggregate instance

reflectionBasedAggregateRootFactory

static StatefulAggregateInstanceFactory reflectionBasedAggregateRootFactory()

Returns an StatefulAggregateInstanceFactory that calls the default no-arguments constructor on the concrete Aggregate type to create a new instance of the Aggregate

Returns:

#DEFAULT_CONSTRUCTOR_AGGREGATE_ROOT_FACTORY

objenesisAggregateRootFactory

static StatefulAggregateInstanceFactory objenesisAggregateRootFactory()

Returns an StatefulAggregateInstanceFactory that uses Objenesis to create a new instance of the Aggregate
Please note: Objenesis doesn't initialize fields nor call any constructors, so you Aggregate design needs to take this into consideration.
All concrete aggregates that extends AggregateRoot have been prepared to be initialized by Objenesis

Returns:

#OBJENESIS_AGGREGATE_ROOT_FACTORY
