IQuery<T>
All Known Implementing Classes:
ArtifactDescriptorQuery, ArtifactKeyQuery, ExpressionMatchQuery, IUProfilePropertyQuery, MatchQuery, OSGiBundleQuery, UserVisibleRootQuery
@Deprecated public interface IMatchQuery<T> extends IQuery<T>
Deprecated.
If possible, use one of the predefined queries in QueryUtil or use the QueryUtil.createMatchQuery(String, Object...) to create a custom expression based query. If the query cannot be expressed using the p2QL, then use a predefined or custom expression query as a first filter (in worst case, use QueryUtil.createIUAnyQuery()) and then provide further filtering like so: 
             for (iter = queryable.query(someExpressionQuery).iterator(); iter.hasNext();) {
                // do your match here
             }
A query in which the elements can be evaluated by calling isMatch on. Each element can be evaluated independently of all other elements. Match queries can be evaluated in parallel as each call isMatch(Object) is mutually
