Class HandlerConfiguration<M>

java.lang.Object
io.fluxzero.common.handling.HandlerConfiguration<M>
Type Parameters:
M - the message wrapper type this configuration applies to
public class HandlerConfiguration<M> extends Object
Configuration object used to define how message handler methods are selected and filtered for a given message type.

This configuration is passed to HandlerInspector and HandlerMatcher instances to determine:

  • Which methods should be considered as valid message handlers,
  • Whether multiple methods on the same target are allowed to handle the same message,
  • And whether a particular message is eligible for handling by a given method.

The generic type M represents the expected message wrapper type (e.g. HasMessage or a subclass).

      Parameters:
      c - the class owning the method
      e - the method to check
      Returns:
      true if the method should be included as a handler

      Retrieves the configured method annotation on the given method, if present.
      Parameters:

      an optional containing the annotation if present, or empty otherwise
