Example 6 with Entry

use of javax.cache.Cache.Entry in project ignite by apache.

the class GAGrid method selectGeneByChromsomeCriteria.

/**
 * method assumes ChromosomeCriteria is set.
 *
 * @param k Gene index in Chromosome
 * @return Primary key of respective Gene
 */
private long selectGeneByChromsomeCriteria(int k) {
    List<Gene> genes = new ArrayList();
    StringBuffer sbSqlClause = new StringBuffer("_val like '");
    sbSqlClause.append("%");
    sbSqlClause.append(config.getChromosomeCriteria().getCriteria().get(k));
    sbSqlClause.append("%'");
    IgniteCache<Long, Gene> cache = ignite.cache(GAGridConstants.GENE_CACHE);
    SqlQuery sql = new SqlQuery(Gene.class, sbSqlClause.toString());
    try (QueryCursor<Entry<Long, Gene>> cursor = cache.query(sql)) {
        for (Entry<Long, Gene> e : cursor) genes.add(e.getValue());
    }
    int idx = selectRandomIndex(genes.size());
    Gene gene = genes.get(idx);
    return gene.id();
}
