Interface Worker<CTX,E extends Exception>

Type Parameters:
CTX - The context type to use, can by any Component, service or POJO.
E - The exception type of the Worker's erroneous termination.

@FunctionalInterface public interface Worker<CTX,E extends Exception>
A Worker represents an (atomic) operation applied to a context and (in contrast to a Command) not returning any result, all of which encapsulated in an object (as of object oriented programming). A Worker is created by a client (e.g. the business logic) and passed to something like a command-bus or command-processor for execution.
