AggregateProcessor

interface AggregateProcessor<C : Any> : AggregateIdCapable, NamedTypedAggregate<C> , MonoMessageProcessor<C, ServerCommandExchange<*>, Mono<DomainEventStream>>

Processor for handling commands on a specific aggregate instance.

This interface defines the contract for processing commands against a particular aggregate, ensuring proper serialization and state management.

Parameters

The type of the command aggregate root.

Inheritors

CommandAggregate

RetryableAggregateProcessor

aggregateId

abstract override val aggregateId: AggregateId

aggregateName

abstract val aggregateName: String

aggregateType

abstract val aggregateType: Class<C>

contextName

abstract val contextName: String

processorName

Functions

aggregateId

fun NamedAggregate.aggregateId(id: String = generateId(), tenantId: String = TenantId.DEFAULT_TENANT_ID): DefaultAggregateId

Creates an AggregateId for this NamedAggregate with the specified parameters.

aggregateType

fun <T> NamedAggregate.aggregateType(): Class<T>?

Finds the aggregate type class associated with this named aggregate.

asAggregateMetadata

fun <C : Any, S : Any> NamedAggregate.asAggregateMetadata(): AggregateMetadata<C, S>

Converts this NamedAggregate to its corresponding AggregateMetadata.

generateId

fun NamedAggregate.generateId(): String
