org.axonframework.messaging.core.configuration.reflection.HandlerDefinitionUtils

public class HandlerDefinitionUtils
extends Object

Utility class that provides methods to register a HandlerDefinition to the ComponentRegistry.

Ensures that the ComponentRegistry at all times has one HandlerDefinition component. Subsequent invocations of registerToComponentRegistry(ComponentRegistry, Function)/registerToComponentRegistry(ComponentRegistry, int, Function) will decorate the existing HandlerDefinition and given HandlerDefinition into a MultiHandlerDefinition.

Only a MultiHandlerDefinition applies a HandlerEnhancerDefinition to created handlers, so every HandlerDefinition registered or decorated through this class is (re)assembled using the current ComponentRegistry's composed HandlerEnhancerDefinition component (see HandlerEnhancerDefinitionUtils). This guarantees the HandlerDefinition component always reflects every configured enhancer, regardless of how many separate calls contributed to either component or in what order.

registerToComponentRegistry

public static void registerToComponentRegistry(ComponentRegistry componentRegistry,
 Function<Configuration,HandlerDefinition> handlerDefinitionBuilder)

Register a HandlerDefinition to the current ComponentRegistry using the given handlerDefinitionBuilder function.

It will be registered with order 0. To register with a different order, use registerToComponentRegistry(ComponentRegistry, int, Function) instead.

Parameters:

componentRegistry - the ComponentRegistry to register the HandlerDefinition to

handlerDefinitionBuilder - the Function that creates the HandlerDefinition based on the Configuration

registerToComponentRegistry

public static void registerToComponentRegistry(ComponentRegistry componentRegistry,
 int order,
 Function<Configuration,HandlerDefinition> handlerDefinitionBuilder)

Register a HandlerDefinition to the current ComponentRegistry using the given handlerDefinitionBuilder function, placing the handlerDefinitionBuilder at the given order.

Parameters:

componentRegistry - the ComponentRegistry to register the HandlerDefinition to

order - the order in which the HandlerDefinition should be registered

handlerDefinitionBuilder - the Function that creates the HandlerDefinition based on the Configuration
