/**
 * An extension of <code>SQLException that provides information
 * about database warnings set on <code>RowSet objects.
 * Warnings are silently chained to the object whose method call
 * caused it to be reported.
 * This class complements the <code>SQLWarning class.
 * <P>
 * Rowset warnings may be retrieved from <code>JdbcRowSet,
 * <code>CachedRowSet™,
 * <code>WebRowSet, FilteredRowSet, or JoinRowSet
 * implementations. To retrieve the first warning reported on any
 * <code>RowSet
 * implementation,  use the method <code>getRowSetWarnings defined
 * in the <code>JdbcRowSet interface or the CachedRowSet
 * interface. To retrieve a warning chained to the first warning, use the
 * <code>RowSetWarning method
 * <code>getNextWarning. To retrieve subsequent warnings, call
 * <code>getNextWarning on each RowSetWarning object that is
 * returned.
 * <P>
 * The inherited methods <code>getMessage, getSQLState,
 * and <code>getErrorCode retrieve information contained in a
 * <code>RowSetWarning object.
