io.fluxzero.common.handling.TypedParameterResolver<Object>

io.fluxzero.sdk.tracking.handling.authentication.UserParameterResolver

All Implemented Interfaces:

ParameterResolver<Object>

public class UserParameterResolver
extends TypedParameterResolver<Object>

Resolves parameters of type User, typically representing the current user in a request context.

This resolver delegates the extraction of user information to a configured UserProvider, which defines how to extract a user from a HasMessage or DeserializingMessage.

If no user can be determined from the message context, the User.getCurrent() thread-local fallback is used.

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(Parameter, 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(Parameter, Annotation, M) is not implemented.
