Example 1 with RyaQuery

use of org.apache.rya.api.persist.query.RyaQuery in project incubator-rya by apache.

the class AccumuloRyaQueryEngine method query.

@Override
public CloseableIteration<RyaStatement, RyaDAOException> query(RyaStatement stmt, AccumuloRdfConfiguration conf) throws RyaDAOException {
    if (conf == null) {

    CloseableIterable<RyaStatement> results = query(ryaQuery);
    return new CloseableIterableIteration<RyaStatement, RyaDAOException>(results);
}

Example 2 with RyaQuery

use of org.apache.rya.api.persist.query.RyaQuery in project incubator-rya by apache.

the class MongoDBRyaDAOIT method testVisibilityStatement.

/**

 * determine if the specified user authorization can view the statement.

 * @param dao - The DAO that will be used by the test.
