public class SimpleCommand
extends CommandEvent

A helper class providing default implementation of the parseLine(java.lang.String[]) and getLine() method of the base CommandEvent class. This command event is intended for commands without a command line, though it simply returns the null String on the getLine() method and returns true on parseLine(java.lang.String[]) if the argument is null.
