46 * A pattern group formed of all public patterns defined in case_study_A.vql.
47 *
48 * <p>Use the static instance as any {@link interface org.eclipse.viatra.query.runtime.api.IQueryGroup}, to conveniently prepare
49 * a VIATRA Query engine for matching all patterns originally defined in file case_study_A.vql,
50 * in order to achieve better performance than one-by-one on-demand matcher initialization.
51 *
52 * <p> From package queries, the group contains the definition of the following patterns: <ul>
53 * <li>inv03</li>
54 * <li>x_inv03_eligAll</li>
55 * <li>x_inv03_hasAll</li>
