Class BuilderBase<B extends BuilderBase<B>>

java.lang.Object
de.team33.patterns.building.elara.BuilderBase<B>
Type Parameters:
B - The builder type: the intended effective type of the concrete builder implementation.
Direct Known Subclasses:
LateBuilder, ProtoBuilder
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 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.
