JCommander (VeraPDF Library GUI 1.4.4-PDFBOX API)

java.lang.Object
- com.beust.jcommander.JCommander

```
public class JCommander
extends Object
```
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.
