Examples of JCommander

com.beust.jcommander.JCommander
The main class for JCommander. It's responsible for parsing the object that contains all the annotated fields, parse the command line and assign the fields with the correct values and a few other helper methods, such as usage(). The object(s) you pass in the constructor are expected to have one or more \@Parameter annotations on them. You can pass either a single object, an array of objects or an instance of Iterable. In the case of an array or Iterable, JCommander will collect the \@Parameter annotations from all the objects passed in parameter. @author cbeust
