package org.axonframework.migration

Class	Description
AddAxonTestFixtureTearDown	Adds @AfterEach void tearDown() { <fixture>.stop(); } to test classes that declare a field of type AxonTestFixture but have no existing @AfterEach (and no method already named tearDown).
AddCommandAnnotation	Scans for methods annotated with @CommandHandler and annotates their command parameter types with @Command.
AddCommandAnnotation.Accumulator
AddEntityCreatorAnnotation	Adds the @EntityCreator annotation to existing no-arg constructors of classes annotated with either @EventSourcedEntity (free AF5) or the Spring stereotype @EventSourced.
AddEventAnnotation	Scans for methods annotated with @EventSourcingHandler and annotates their event payload types with @Event.
AddEventAnnotation.Accumulator
AddEventTagAnnotation	Adds @EventTag(key = "<EntitySimpleName>") to the aggregate-identifier field of every event class used in @EventSourcingHandler methods.
AddEventTagAnnotation.Accumulator	Maps event-class FQN → scan result needed to place @EventTag.
AnnotateObsoleteSequencingPolicyProperty	Spring-Boot-only advisory recipe for the AF4 → AF5 sequencing-policy migration.
Axon4ToAxon5QueryResponseTypes	Unwraps Axon Framework 4 ResponseTypes wrappers on AF5-shape (typed-payload, two-argument) J.MethodInvocation calls against QueryGateway.
ConfigureEventSourcedAnnotation	Adds explicit tagKey and idType attributes to @EventSourced annotations that do not yet configure them.
ConfigureEventSourcedAnnotation.Accumulator	Records enclosingClassFqn → idTypeFqn for every @AggregateIdentifier field.
ConvertCommandHandlerConstructorToCompanionObject	Kotlin counterpart to ConvertCommandHandlerConstructorToStaticMethod.
ConvertCommandHandlerConstructorToStaticMethod	Rewrites Axon Framework 4 @CommandHandler constructors into static handle methods, the AF5 idiom for "creational" command handlers.
MigrateAggregateTestFixtureSetup	Rewrites the AF4 aggregate-fixture constructor expression new AggregateTestFixture<X>(X.class) (or its diamond form) to the AF5 fluent factory:
MigrateAxonTestFixtureFluentApi	Rewrites AF4 AggregateTestFixture test method bodies to the AF5 AxonTestFixture fluent given/when/then API.
MigrateCommandGatewayInEventHandler	Migrates an Axon Framework 4 event-handling component that dispatches commands via a class-level CommandGateway field to the AF5 in-handler pattern: a method-parameter CommandDispatcher.
MigrateKotlinDslBomImport	Rewrites Kotlin DSL Spring Dependency Management mavenBom(...) imports whose version is supplied via Kotlin string-template indirection (typically ${property("axonFrameworkVersion")} read from an extra["axonFrameworkVersion"] declaration).
MigrateMessageInterceptorSignatures	Migrates the method signatures of MessageHandlerInterceptor and MessageDispatchInterceptor implementations to their Axon Framework 5 shape, while leaving the method body untouched.
MigrateSequencingPolicyLambda	Rewrites single-argument SequencingPolicy lambdas to the AF5 two-argument shape with an Optional return.
MigrateSnapshotTriggerDefinitionToAnnotation	Migrates the AF4 Spring Boot snapshotting configuration to the AF5 @Snapshotting annotation.
MigrateSnapshotTriggerDefinitionToAnnotation.Accumulator	Cross-file accumulator populated during the scan phase.
MigrateSnapshotTriggerDefinitionToAnnotation.SnapshotBeanInfo	Metadata collected for a single @Bean SnapshotTriggerDefinition method.
MigrateSnapshotTriggerDefinitionToAnnotation.TriggerType	Classification of a scanned SnapshotTriggerDefinition bean.
RemoveTypeArguments	Strips generic type arguments from references to a specific fully-qualified type.
ReplaceAggregateLifecycleApply	Replaces calls to AggregateLifecycle.apply(...) with calls to eventAppender.append(...) on an injected EventAppender parameter, matching the AF5 entity migration pattern documented at docs/reference-guide/.../paths/aggregates/index.adoc.
UpgradeJava	Bumps the Java compiler target to a configurable LTS, with validation that the target satisfies the Axon Framework 5 minimum (Java 21).
UpgradeKotlin	Bumps Kotlin to a configurable 2.x line, with validation that the target satisfies the Axon Framework 5 minimum (Kotlin 2.0).
