SimpleStateDomainEventExchange

class SimpleStateDomainEventExchange<S : Any, T : Any>(val state: ReadOnlyStateAggregate<S>, val message: DomainEvent<T>, val attributes: MutableMap<String, Any> = ConcurrentHashMap()) : StateDomainEventExchange<S, T>

Simple implementation of StateDomainEventExchange.

This class provides a basic implementation of the StateDomainEventExchange interface, combining a read-only state aggregate with a domain event message and managing exchange attributes.

Type Parameters

The type of the aggregate state

The type of the domain event body

Constructors

SimpleStateDomainEventExchange

constructor(state: ReadOnlyStateAggregate<S>, message: DomainEvent<T>, attributes: MutableMap<String, Any> = ConcurrentHashMap())

Creates a new SimpleStateDomainEventExchange with state, message, and attributes

Properties

attributes

open override val attributes: MutableMap<String, Any>

Mutable map for storing exchange attributes (default: empty ConcurrentHashMap)

message

open override val message: DomainEvent<T>

The domain event being processed

state

open override val state: ReadOnlyStateAggregate<S>

The read-only state aggregate

Functions

acknowledge

open fun acknowledge(): Mono<Void>

clearError

open override fun clearError()

Clears the current error object.

confirmLocalDelivery

fun MessageExchange<*, *>.confirmLocalDelivery()

Confirms that this receiver synchronously admitted the local exchange.

extractDeclared

open override fun <T : Any> extractDeclared(type: Class<T>): T?

Extracts an object of the specified type from the exchange context.

extractObject

open fun <T : Any> extractObject(type: KType): T?

getAggregateVersion

open fun getAggregateVersion(): Int?

getAttribute

open fun <T> getAttribute(key: String): T?

getCommandResult

open override fun getCommandResult(): Map<String, Any>

open override fun <R> getCommandResult(key: String): R?

getCommandStream

fun DomainEventExchange<*>.getCommandStream(): CommandStream?

Retrieves the command stream from the domain event exchange attributes.

getError

open override fun getError(): Throwable?

Gets the current error object.

getEventFunction

open fun getEventFunction(): MessageFunction<Any, DomainEventExchange<*>, Mono<*>>?

Retrieves the event processing function for this exchange.

getFunction

open fun getFunction(): FunctionInfo?

getFunctionAs

open fun <FUN : FunctionInfo> getFunctionAs(): FUN?

getServiceProvider

open fun getServiceProvider(): ServiceProvider?

rejectLocalDelivery

fun MessageExchange<*, *>.rejectLocalDelivery()

Rejects local-only suppression when this exchange is filtered or cannot be admitted. The distributed copy then remains eligible for processing.

removeAttribute

open fun removeAttribute(key: String): DomainEventExchange<T>

setAttribute

open fun setAttribute(key: String, value: Any): DomainEventExchange<T>

setCommandResult

open override fun setCommandResult(key: String, value: Any)

setCommandStream

fun DomainEventExchange<*>.setCommandStream(commandStream: CommandStream): DomainEventExchange<*>

Sets the command stream in the domain event exchange attributes. This allows the command stream to be associated with the domain event for later retrieval.

setError

open override fun setError(throwable: Throwable)

Sets the error object for this context.

setFunction

open fun setFunction(functionInfo: FunctionInfo): DomainEventExchange<T>

setServiceProvider

open fun setServiceProvider(serviceProvider: ServiceProvider): DomainEventExchange<T>

SimpleStateDomainEventExchange
