UnknownNameException

All Implemented Interfaces:
  `Serializable`

public class UnknownNameException extends IllegalArgumentException
Thrown when an operation cannot complete because a given name is unrecognized. The unrecognized name may be a `GenericName`, an `Identifier`, a `String` used as a name or identifier, or any other objects with similar purpose.

Note: in the particular case of objects created from a `Factory`, the exception for unrecognized identifiers is rather `NoSuchIdentifierException`. This `UnknownNameException` differs in being an unchecked exception.
