ControlNumberGenerator.AbstractBuilder (controlnumbers 0.0.3 API)

java.lang.Object
- de.pseudonymisierung.controlnumbers.ControlNumberGenerator.AbstractBuilder<T>

Type Parameters:

T - The type of objects built by an implementation of this class.

Direct Known Subclasses:

ControlNumberGenerator.Builder, EncryptedControlNumberGenerator.Builder

Enclosing class:

ControlNumberGenerator
```
public abstract static class ControlNumberGenerator.AbstractBuilder<T extends ControlNumberGenerator>
extends Object
```
Abstraction of a builder class. This is needed to implement builders for ControlNumberGenerator and EncryptedControlNumberGenerator, which generate instances of the respective classes, while keeping common code in one place. (see https://stackoverflow.com/questions/21086417/builder-pattern-and-inheritance). Implementations should set T to a fixed class.
