Worker (org.refcodes:refcodes-command 2.2.0 API)

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.

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@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.

    Parameters:
    
    aContext - The target object (being a service, a Component or a POJO) which is used by the Worker to perform its (atomic) operation.
