Let me give you an example: </p> <p> ! Suppose you have a data structure that maintains a list of camp sites, with the ! facilities they provide. With JavaMatch, your web site can offer a "detailed ! search" feature, where a user can specify which one of the facilities he wants or ! doesn't want on the site. ! </p> ! <p> ! Let's assume a user wants to look for a small, cheap camp site with a swimming pool. ! The following code defines and executes this match query: ! </p> ! <pre class="source">QuerySet query = new QuerySet(); ! query.addPreferred(new LessThan("size", 100)); ! query.addPreferred(new NumberEquals("distanceToSwimmingPool", 0)); ! query.addPreferred(new Minimum("priceIndication")); ! ! List campSites = guide.getCampSites(); ! MatchResult matchResult = matchEngine.executeQuery(query, campSites);</pre> ! <p> ! Class MatchResult contains a list of ResultItem's. A ResultItem consists of a ! matchedObject, the object that was matched, and a matchValue, an indication of how ! good this object matches the specified criteria). The ResultItems are sorted in ! decreasing order by their matchValue, so the best matching object is the first one ! in the list. ! </p> ! <p> ! The full source can be found in the directory examples/camping in the distribution </p> - <h2>Example 2: Results and extensions</h2> - <p> - The JavaMatch engine is domain-independent, so if I want to look for a certain - second-hand car, I can specify the following query: - </p> <pre class="source">QuerySet query = new QuerySet(); query.addRequired(new StringEquals("brand", "BMW")); - query.addPreferred(new Range("buildYear", 1997, 2002)); query.addPreferred(new LessThan("price", 10000)); query.addPreferred(new LessThan("mileage", 80000)); --- 23,40 ---- matching objects. </p> ! <h2>Example: Queries</h2> <p> Nice those stories, but how does it work in practice?

You may want to find a match with more complicated, domain-specific criteria, ! for example if the car has had regular service intervals. In this case, you can ! create your own queries by extending class MatchQuery, or one of its subclasses. !
