Interface Summary

Interface	Description
HandlerDefinition	Interface that describes an object capable of inspecting a method to determine if the method is suitable for message handling.
HandlerEnhancerDefinition	Interface describing objects that are capable of enhancing a MessageHandler, giving it additional functionality.
MessageHandlingMember<T>	Interface describing a handler for specific messages targeting entities of a specific type.
ParameterResolver<T>	Interface for a mechanism that resolves handler method parameter values from a given Message.
ParameterResolverFactory	Interface for objects capable of creating Parameter Resolver instances for annotated handler methods.

Class Summary

Class	Description
AbstractAnnotatedParameterResolverFactory<A extends Annotation,P>	ParameterResolverFactory that will supply a parameter resolver when a matching parameter annotation is paired with a suitable type of parameter.
AnnotatedHandlerInspector<T>	Inspector for a message handling target of type T that uses annotations on the target to inspect the capabilities of the target.
AnnotatedMessageHandlingMember<T>	Implementation of a MessageHandlingMember that is used to invoke message handler methods on the target type.
AnnotatedMessageHandlingMemberDefinition	The default HandlerDefinition implementation in Axon.
ClasspathHandlerDefinition	HandlerDefinition instance that locates other HandlerDefinition instances on the class path.
ClasspathHandlerEnhancerDefinition	HandlerEnhancerDefinition instance that locates other HandlerEnhancerDefinition instances on the class path.
ClasspathParameterResolverFactory	ParameterResolverFactory instance that locates other ParameterResolverFactory instances on the class path.
DefaultParameterResolverFactory	Factory for the default parameter resolvers.
FixedValueParameterResolver<T>	ParameterResolver implementation that injects a fixed value.
HandlerComparator	Comparator used by AnnotatedHandlerInspector to sort entity members.
MessageIdentifierParameterResolverFactory	An extension of the AbstractAnnotatedParameterResolverFactory that accepts parameters of a String type that are annotated with the MessageIdentifier annotation and assigns the identifier of the Message.
MultiHandlerDefinition	HandlerDefinition instance that delegates to multiple other instances, in the order provided.
MultiHandlerEnhancerDefinition	HandlerEnhancerDefinition instance that delegates to multiple other instances, in the order provided.
MultiParameterResolverFactory	ParameterResolverFactory instance that delegates to multiple other instances, in the order provided.
PayloadParameterResolver	Implementation of a ParameterResolver that resolves the Message payload as parameter in a handler method.
SimpleResourceParameterResolverFactory	A ParameterResolverFactory implementation for simple resource injections.
WrappedMessageHandlingMember<T>	Abstract implementation of a MessageHandlingMember that delegates to a wrapped MessageHandlingMember.

Exception Summary

Exception	Description
MessageHandlerInvocationException	MessageHandlerInvocationException is a runtime exception that wraps an exception thrown by an invoked message handler.
UnsupportedHandlerException	Thrown when an @...Handler annotated method was found that does not conform to the rules that apply to those methods.

Annotation Types Summary

Annotation Type	Description
MessageHandler	Annotation indicating that a member method should be able to respond to Messages.
MessageIdentifier	Annotation indication that a parameter on a Message Handler method should be injected with the identifier of a Message.
MetaDataValue	Annotation that indicates the parameter needs to be resolved to the value of the Message MetaData stored under the given key.
