Class ArgumentProcessor

java.lang.Object

org.jruby.util.cli.ArgumentProcessor

public class ArgumentProcessor
extends Object

Encapsulated logic for processing JRuby's command-line arguments. This class holds the processing logic for JRuby's non-JVM command-line arguments. All standard Ruby options are processed here, as well as nonstandard JRuby- specific options. Options passed directly to the JVM are processed separately, by either a launch script or by a native executable.
