IParentProvider (ph-commons 11.1.0 API)

Type Parameters:

PARENTTYPE - The type of object to get a parent from

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 IParentProvider<PARENTTYPE>
```
This helper interface is required to build a generic tree. This is required because the used interfaces do not provide a base interface implementing a getParent method.
