Interface SqlRowSet

All Superinterfaces:

Serializable

All Known Implementing Classes:

ResultSetWrappingSqlRowSet

public interface SqlRowSet
extends Serializable

Mirror interface for RowSet, representing disconnected ResultSet data.

The main difference to the standard JDBC RowSet is that a SQLException is never thrown here. This allows a SqlRowSet to be used without having to deal with checked exceptions. A SqlRowSet will throw Spring's InvalidResultSetAccessException instead (when appropriate).

Note: This interface extends the java.io.Serializable marker interface. Implementations, which typically hold disconnected data, are encouraged to be actually serializable (as far as possible).
