Exception thrown during option processing upon discovery that an argument is invalid.

Exception thrown during option processing upon discovery that a mandatory argument is missing.

An Option comprises an enumerated type which defines the domain of the option, the keywords which parsers may use to identify the option, an end-user friendly description of the option, and an action that should be performed each time that the option is set.

Exception thrown during option processing.

An OptionProcessor serves primarily to support command-line argument processing, but may occasionally prove useful in other circumstances.

An OptionProcessorFactory enables a client to dynamically specify and assemble an option processor. In particular, the factory allows a client to flexibly define a particular option processor while ignoring specification and evaluation order dependency. Validation is postponed until final assembly time, at which time a [ValidationException] will be thrown in the event of incorrect or incomplete specification; otherwise, the constructed option processor provably reflects the client specification.

Exception thrown during option processing upon discovery of an unrecognized option keyword.

Exception thrown by the factory's validation process in the event that the client-specified option processor fails validation.
