io.fluxzero.sdk.tracking.handling.PayloadParameterResolver

public class PayloadParameterResolver extends Object

Resolves handler method parameters by injecting the message payload.

This resolver matches a parameter when its declared type is assignable from the actual payload class of the incoming message.

This resolver is typically used in conjunction with filters such as PayloadFilter to determine handler compatibility based on payload types.

Special care is taken to allow null payloads for parameters that are declared nullable, which can occur during upcasting or transformation pipelines.

Method Details
- matches
  
  public boolean matches(Parameter p, Annotation methodAnnotation, HasMessage value)
- resolve
  
  public Function<HasMessage, Object> resolve(Parameter p, Annotation methodAnnotation)
- test
  
  public boolean test(HasMessage message, Parameter parameter)
- determinesSpecificity
  
  public boolean determinesSpecificity()
  
  Indicates that this resolver contributes to disambiguating handler methods when multiple handlers are present in the same target class.
  This is useful when more than one method matches a message, and the framework must decide which method is more specific. If this returns true, the resolver's presence and compatibility with the parameter may influence which handler is selected.
  
  Returns:
  
  true, signaling that this resolver helps determine method specificity
- mayApply
  
  default boolean mayApply(Executable arg0, Class<?> arg1)
