io.fluxcapacitor.javaclient.tracking.handling.DeserializingMessageParameterResolver

All Implemented Interfaces:

ParameterResolver<Object>

public class DeserializingMessageParameterResolver
extends TypedParameterResolver<Object>

Resolves handler method parameters of type DeserializingMessage.

This allows handler methods to access the deserialization context, including message metadata, payload, and raw serialized content.

Useful when advanced information about the message is needed, such as the Flux-assigned message index.

public Function<Object,Object> resolve(Parameter p,
 Annotation methodAnnotation)

Description copied from interface: ParameterResolver

Resolves a Parameter of a handler method into a value function based on the given message.

If the parameter cannot be resolved by this resolver and ParameterResolver.matches(java.lang.reflect.Parameter, java.lang.annotation.Annotation, M) is not implemented, this method must return null.

Parameters:

p - the parameter to resolve

methodAnnotation - the annotation present on the handler method (e.g., @HandleEvent)

Returns:

a function that takes a message and returns a value to be injected into the method parameter, or null if the parameter cannot be resolved and ParameterResolver.matches(java.lang.reflect.Parameter, java.lang.annotation.Annotation, M) is not implemented.
