Examples of org.hibernate.search.filter.FilterKey

org.hibernate.search.filter.FilterKey
The key object must implement equals / hashcode so that 2 keys are equals if and only if the given Filter types are the same and the set of parameters are the same.
The FilterKey creator (ie the @Key method) does not have to inject impl It will be done by Hibernate Search @author Emmanuel Bernard

      return instance;

   private FilterKey createFilterKey(FilterDef def, Object instance) {
      FilterKey key = null;
      if (!cacheInstance(def.getCacheMode())) {
         return key; // if the filter is not cached there is no key!
      }


      if (def.getKeyMethod() == null) {
         key = new FilterKey() {
            public int hashCode() {
               return getImpl().hashCode();
