com.martiansoftware.jsap.stringparsers.ForNameStringParser

public class ForNameStringParser
extends StringParser

A StringParser that passes the argument to a static method of signature forName(String) of a specified class.

Note that, for instance, this parser can be used with Class (resulting in a string parser identical to ClassStringParser), but also Charset, and more generally, any class using the forName(String) convention.
