Type Parameters:

B - The builder type: the intended effective type of the concrete builder implementation.

public class BuilderBase<B extends BuilderBase<B>>
extends Object

Base class of a generic class hierarchy that has a type parameter intended to represent the effective type of a concrete implementation.

The main purpose is the realization of a generic builder pattern, whereby there should be methods that should result in this - i.e. the builder instance itself - in order to chain further method calls. For this purpose, it should be ensured in the constructor that this actually corresponds to the designated type.
