示例1: createSegment

import java.sql.ResultSet; //导入方法依赖的package包/类
private S createSegment(ResultSet rs, boolean geometry) throws SQLException {
	boolean createfullWaySegment = false;
	
	if (rs.isAfterLast()) {
		return null;
	}
	
	int i = 1;
	while (!createfullWaySegment && i <= rs.getMetaData().getColumnCount()) {
		if (rs.getMetaData().getColumnLabel(i).startsWith(QUERY_PREFIX)) {
			createfullWaySegment = true;
		}
		i++;
	}
	
	long segmentId = rs.getLong("id");

	// TODO: use factory?
	S segment;
	
	if (createfullWaySegment) {
	
		IWaySegment waySegment = new WaySegment();
		waySegment.setId(segmentId);

		mapSegment(waySegment, rs);

		if (geometry) {
			waySegment.setGeometry((LineString) bp.parse(rs.getBytes(QUERY_PREFIX + "_geometry_ewkb")));

示例2: loadSequentialRowsForward

import java.sql.ResultSet; //导入方法依赖的package包/类
/**
 * Loads a single logical row from the result set moving forward.  This is the
 * processing used from the ScrollableResults where there were collection fetches
 * encountered; thus a single logical row may have multiple rows in the underlying
 * result set.
 *
 * @param resultSet The result set from which to do the load.
 * @param session The session from which the request originated.
 * @param queryParameters The query parameters specified by the user.
 * @param returnProxies Should proxies be generated
 * @return The loaded "row".
 * @throws HibernateException
 */
public Object loadSequentialRowsForward(
		final ResultSet resultSet,
		final SessionImplementor session,
		final QueryParameters queryParameters,
		final boolean returnProxies) throws HibernateException {

	// note that for sequential scrolling, we make the assumption that
	// the first persister element is the "root entity"

	try {
		if ( resultSet.isAfterLast() ) {
			// don't even bother trying to read further
			return null;
		}

		if ( resultSet.isBeforeFirst() ) {
			resultSet.next();
		}

		// We call getKeyFromResultSet() here so that we can know the
		// key value upon which to perform the breaking logic.  However,
		// it is also then called from getRowFromResultSet() which is certainly
		// not the most efficient.  But the call here is needed, and there
		// currently is no other way without refactoring of the doQuery()/getRowFromResultSet()
		// methods
		final EntityKey currentKey = getKeyFromResultSet(
				0,
				getEntityPersisters()[0],
				null,
				resultSet,
				session
			);

		return sequentialLoad( resultSet, session, queryParameters, returnProxies, currentKey );
	}
	catch ( SQLException sqle ) {

				sqle,
				"could not perform sequential read of results (forward)",
				getSQLString()
			);
