Examples of org.eclipse.persistence.queries.QueryResultsCachePolicy

org.eclipse.persistence.queries.QueryResultsCachePolicy
PUBLIC: A QueryResultsCache policy dictates how a query's results will be cached. It allows an invalidation policy and a maximum number of results to be set. Query results are cached based on the parameter values of a query, and the maximum number of results refers to the maximum number of parameter sets results will be ached for. @see org.eclipse.persistence.queries.ReadQuery#setQueryCachePolicy(QueryResultsCachePolicy)

        // Process JPA named queries and add as session queries,
        // this must be done after descriptor init as requires to parse the JPQL.
        processJPAQueries();
        
        // Configure default query cache for all named queries.
        QueryResultsCachePolicy defaultQueryCachePolicy = getProject().getDefaultQueryResultsCachePolicy();
        if (defaultQueryCachePolicy != null) {
            for (List<DatabaseQuery> queries : getQueries().values()) {
                for (DatabaseQuery query : queries) {
                    if (query.isReadQuery() && (query.getDescriptor() != null) && !query.getDescriptor().getCachePolicy().isIsolated()) {
                        ReadQuery readQuery = (ReadQuery)query;
                        if (!readQuery.shouldCacheQueryResults()) {
                            readQuery.setQueryResultsCachePolicy(defaultQueryCachePolicy.clone());
                        }
