All Implemented Interfaces:
Predicate<String>
public final class ISBNValidator extends Object implements 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.
