Interface HandlerMethodPlan<M>

Type Parameters:
M - the message type used by the handling pipeline
All Superinterfaces:
HandlerDescriptor
public interface HandlerMethodPlan<M> extends HandlerDescriptor
A reusable plan for invoking one already selected handler method.

A plan contains the method, its argument-resolution strategy, and either a fixed handler target or a strategy for obtaining that target from the current HandlerInput. For example, a self-handling payload plan obtains its target from HandlerInput.getPayload() on every invocation. Implementations must be immutable and safe for concurrent use.
