Interface Pojo

public interface Pojo

This interface is only used for documentation of what is meant by the term POJO:
A POJO is a shortcut for Plain Old Java Object and simply means any Java object containing or providing data. While the java beans specification is generally a good idea to follow, it is sometimes too restrictive. E.g. you might want to name a boolean getter with the prefix "has" or want to have a primitive type as setter argument while the getter has the according object type. A POJO is NOT limited by such restrictions. However the following conventions should be considered:

• You should NOT have two setter-methods with the same name in the same class. If you have setFoo(Foo foo) do NOT add setFoo(String foo). Simply add setFooAsString(String fooAsString) instead.
• A Pojo should have a public non-argument constructor. However this is NOT always suitable especially for data-types that should be immutable and therefore require constructor parameters rather than setter-methods. Otherwise you might need to provide custom-logic to the implementation of PojoFactory in order to create instances of that Pojo with the utilities offered here.

ATTENTION:
Do NOT use this interface in your code. Its only purpose is to document the meaning of the term POJO.
