Class Option

java.lang.Object
com.martiansoftware.jsap.Parameter
com.martiansoftware.jsap.Option
Direct Known Subclasses:
FlaggedOption, UnflaggedOption

public abstract class Option
extends Parameter
The base class from which FlaggedOption and UnflaggedOption are derived. An Option is a Parameter that requires some information (unlike a Switch whose mere presence is significant).

Options may be declared as lists, or multiple values separated by a delimiting character. An example of a list option might be a classpath, which is a collection of paths separated by a ":" on *nix systems and a ";" on DOS/Windows systems. JSAP automatically separates list options into multiple tokens before calling their StringParsers' parse() method.

The default list separator is JSAP.DEFAULT_LISTSEPARATOR, which is defined as the platform's path separator character (":" on *nix and ";" on DOS/Windows as described above).
