protected AggregateConfigurer(Class<A> aggregate)
```
    Creates a default configuration as described in defaultConfiguration(Class). This constructor is available for subclasses that provide additional configuration possibilities.
    
    Parameters:
    
    aggregate - The type of aggregate to configure
- Method Detail
  - defaultConfiguration
```
public static <A> AggregateConfigurer<A> defaultConfiguration(Class<A> aggregateType)
```
    Creates a default Configuration for an aggregate of the given aggregateType. This required either a Repository to be configured using configureRepository(Function), or that the Global Configuration contains an Event Store and the Aggregate support Event Sourcing.
    
    Type Parameters:
    
    A - The type of Aggregate to configure
    
    Parameters:
    
    aggregateType - The type of Aggregate to configure
    
    Returns:
    
    An AggregateConfigurer instance for further configuration of the Aggregate
  - jpaMappedConfiguration
```
public static <A> AggregateConfigurer<A> jpaMappedConfiguration(Class<A> aggregateType)
```
    Creates a Configuration for an aggregate of given aggregateType, which is mapped to a relational database using an EntityManager obtained from the main configuration. The given aggregateType is expected to be a proper JPA Entity.
    The EntityManagerProvider is expected to have been registered with the Configurer (which would be the case when using DefaultConfigurer.jpaConfiguration(EntityManagerProvider). If that is not the case, consider using jpaMappedConfiguration(Class, EntityManagerProvider) instead.
    
    Type Parameters:
    
    A - The type of Aggregate to configure
    
    Parameters:
    
    aggregateType - The type of Aggregate to configure
    
    Returns:
    
    An AggregateConfigurer instance for further configuration of the Aggregate
  - jpaMappedConfiguration
```
public static <A> AggregateConfigurer<A> jpaMappedConfiguration(Class<A> aggregateType,
                                                                EntityManagerProvider entityManagerProvider)
```
    Creates a Configuration for an aggregate of given aggregateType, which is mapped to a relational database using an EntityManager provided by given entityManagerProvider. The given aggregateType is expected to be a proper JPA Entity.
    
    Type Parameters:
    
    A - The type of Aggregate to configure
    
    Parameters:
    
    aggregateType - The type of Aggregate to configure
    
    entityManagerProvider - The provider for Axon to retrieve the EntityManager from
    
    Returns:
    
    An AggregateConfigurer instance for further configuration of the Aggregate
  - configureRepository
```
public AggregateConfigurer<A> configureRepository(Function<Configuration,Repository<A>> repositoryBuilder)
```
    Defines the repository to use to load and store Aggregates of this type. The builder function receives the global configuration object from which it can retrieve components the repository depends on.
    
    Parameters:
    
    repositoryBuilder - The builder function for the repository
    
    Returns:
    
    this configurer instance for chaining
  - configureAggregateFactory
```
public AggregateConfigurer<A> configureAggregateFactory(Function<Configuration,AggregateFactory<A>> aggregateFactoryBuilder)
```
    Defines the factory to use to to create new Aggregates instances of the type under configuration.
    
    Parameters:
    
    aggregateFactoryBuilder - The builder function for the AggregateFactory
    
    Returns:
    
    this configurer instance for chaining
  - configureCommandHandler
```
public AggregateConfigurer<A> configureCommandHandler(Function<Configuration,AggregateAnnotationCommandHandler> aggregateCommandHandlerBuilder)
```
    Defines the AggregateAnnotationCommandHandler instance to use.
    
    Parameters:
    
    aggregateCommandHandlerBuilder - The builder function for the AggregateCommandHandler
    
    Returns:
    
    this configurer instance for chaining
  - configureCommandTargetResolver
```
public AggregateConfigurer<A> configureCommandTargetResolver(Function<Configuration,CommandTargetResolver> commandTargetResolverBuilder)
```
    Defines the CommandTargetResolver to use for the Aggregate type under configuration. The CommandTargetResolver defines which Aggregate instance must be loaded to handle a specific Command.
    
    Parameters:
    
    commandTargetResolverBuilder - the builder function for the CommandTargetResolver.
    
    Returns:
    
    this configurer instance for chaining
  - configureSnapshotTrigger
```
public AggregateConfigurer<A> configureSnapshotTrigger(Function<Configuration,SnapshotTriggerDefinition> snapshotTriggerDefinition)
```
    Configures snapshotting for the Aggregate type under configuration.
    Note that this configuration is ignored if a custom repository instance is configured.
    
    Parameters:
    
    snapshotTriggerDefinition - The function creating the SnapshotTriggerDefinition
    
    Returns:
    
    this configurer instance for chaining
