Examples of org.hsqldb_voltpatches.result.Result

org.hsqldb_voltpatches.result.Result
The primary unit of communication between Connection, Server and Session objects. An HSQLDB Result object encapsulates all requests (such as to alter or query session settings, to allocate and execute statements, etc.) and all responses (such as exception indications, update counts, result sets and result set metadata). It also implements the HSQL wire protocol for comunicating all such requests and responses across the network. Uses a navigator for data. @author Campbell Boucher-Burnett (boucherb@users dot sourceforge.net) @author Fred Toussi (fredt@users dot sourceforge.net) @version 1.9.0 @since 1.9.0
