org.klojang.check.aux.DuplicateValueException

All Implemented Interfaces:

Serializable

public class DuplicateValueException
extends RuntimeException

Indicates that insertion into a Map, Set or some other uniqueness-enforcing data structure failed because the value to be inserted turned out to be a duplicate. Klojang Check does not itself ever throw a DuplicateValueException, but the error condition it represents is general and important enough to merit inclusion as a common exception in the CommonExceptions class.

 Check.that(arg).isNot(keyIn(), map, duplicateKey(arg));
