Method Detail

inspectType

public static <T> AnnotatedHandlerInspector<T> inspectType(Class<? extends T> handlerType)

Create an inspector for given handlerType that uses a ClasspathParameterResolverFactory to resolve method parameters and ClasspathHandlerDefinition to create handlers.

Type Parameters:

T - the handler's type

Parameters:

handlerType - the target handler type

Returns:

a new inspector instance for the inspected class

inspectType

public static <T> AnnotatedHandlerInspector<T> inspectType(Class<? extends T> handlerType,
                                                           ParameterResolverFactory parameterResolverFactory)

Create an inspector for given handlerType that uses given parameterResolverFactory to resolve method parameters.

Type Parameters:

T - the handler's type

Parameters:

handlerType - the target handler type

parameterResolverFactory - the resolver factory to use during detection

Returns:

a new inspector instance for the inspected class

inspectType

public static <T> AnnotatedHandlerInspector<T> inspectType(Class<? extends T> handlerType,
                                                           ParameterResolverFactory parameterResolverFactory,
                                                           HandlerDefinition handlerDefinition)

Create an inspector for given handlerType that uses given parameterResolverFactory to resolve method parameters and given handlerDefinition to create handlers.

Type Parameters:

T - the handler's type

Parameters:

handlerType - the target handler type

parameterResolverFactory - the resolver factory to use during detection

handlerDefinition - the handler definition used to create concrete handlers

Returns:

a new inspector instance for the inspected class

inspectType

public static <T> AnnotatedHandlerInspector<T> inspectType(Class<? extends T> handlerType,
                                                           ParameterResolverFactory parameterResolverFactory,
                                                           HandlerDefinition handlerDefinition,
                                                           Set<Class<? extends T>> declaredSubtypes)

Create an inspector for given handlerType and its declaredSubtypes that uses given parameterResolverFactory to resolve method parameters and given handlerDefinition to create handlers.

Type Parameters:

T - the handler's type

Parameters:

handlerType - the target handler type

parameterResolverFactory - the resolver factory to use during detection

handlerDefinition - the handler definition used to create concrete handlers

declaredSubtypes - the declared subtypes of this handlerType

Returns:

a new inspector instance for the inspected class

inspect

public <C> AnnotatedHandlerInspector<C> inspect(Class<? extends C> entityType)

Inspect another handler type and register the result to the inspector registry of this inspector. This is used by Axon to inspect child entities of an aggregate.

Type Parameters:

C - the handler's type

Parameters:

entityType - the type of the handler to inspect

Returns:

a new inspector for the given type

getHandlers

@Deprecated
public List<MessageHandlingMember<? super T>> getHandlers()

Deprecated. use getAllHandlers() or getHandlers(Class) instead

Returns a list of detected members of the inspected entity that are capable of handling certain messages.

Returns:

a list of detected message handlers

getHandlers

public Stream<MessageHandlingMember<? super T>> getHandlers(Class<?> type)

Returns a list of detected members of given type that are capable of handling certain messages.

Parameters:

type - a type of inspected entity

Returns:

a stream of detected message handlers for given type

chainedInterceptor

public MessageHandlerInterceptorMemberChain<T> chainedInterceptor(Class<?> type)

Returns an Interceptor Chain of annotated interceptor methods defined on the given type. The given chain will invoke all relevant interceptors in an order defined by the handler definition.

Parameters:

type - The type containing the handler definitions

Returns:

an interceptor chain that invokes the interceptor handlers defined on the inspected type

getAllHandlers

public Map<Class<?>,SortedSet<MessageHandlingMember<? super T>>> getAllHandlers()

Gets all handlers per type for inspected entity. Handlers are sorted based on HandlerComparator.

Returns:

a map of handlers per type

getAllInterceptors

public Map<Class<?>,SortedSet<MessageHandlingMember<? super T>>> getAllInterceptors()

Returns a Map of all registered interceptor methods per inspected type. Each entry contains the inspected type as key, and a SortedSet of interceptor methods defined on that type, in the order they are considered for invocation.

Returns:

a map of interceptors per type
