/**
* Mirror interface for <code>javax.sql.RowSet</code>, representing
* disconnected <code>java.sql.ResultSet</code> data.
*
* <p>The main difference to the standard JDBC RowSet is that an 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
* <code>org.springframework.jdbc.InvalidResultSetAccessException</code>
* instead (when appropriate).
*
* <p>Note: This interface extends the <code>java.io.Serializable</code>
* marker interface. Implementations, which typically hold disconnected data,
* are encouraged to be actually serializable (as far as possible).
