Examples of org.apache.commons.cli.CommandLine

org.apache.commons.cli.CommandLine

Represents list of arguments parsed against a {@link Options} descriptor.
It allows querying of a boolean {@link #hasOption(String opt)}, in addition to retrieving the {@link #getOptionValue(String opt)}for options requiring arguments.

Additionally, any left-over or unrecognized arguments, are available for further processing.
