ISBNValidator (ISBN Validation 1.0.1 API)

java.lang.Object
- de.creativecouple.validation.isbn.ISBNValidator

All Implemented Interfaces:

java.util.function.Predicate<String>
```
public final class ISBNValidator
extends Object
implements java.util.function.Predicate<String>
```
The ISBNValidator class represents a combination of rules for the desired ISBN length (10 or 13) and hyphenation style (any, none, correct, correct-or-none), for checking input strings.
E.g. myValidator = ISBNValidator.isbn13().hyphenation(NONE) to validate compact ISBN-13 string only.
