/**
* 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 {@code setFoo(Foo foo)}
* do NOT add {@code setFoo(String foo)}. Simply add {@code setFooAsString(String fooAsString)} instead.
* - A {@link Pojo} should have a public non-argument constructor. Otherwise consider
* {@link net.sf.mmm.util.lang.api.Datatype} or use {@link PojoFactory} to provide custom-logic to the implementation in
* order to create instances of your {@link Pojo} with the utilities offered here.
