## Class ResultSetWrappingSqlRowSetMetaData

- java.lang.Object
- - org.springframework.jdbc.support.rowset.ResultSetWrappingSqlRowSetMetaData

- All Implemented Interfaces:
    SqlRowSetMetaData

      public class ResultSetWrappingSqlRowSetMetaData
      extends Object
      implements SqlRowSetMetaData

  Default implementation of Spring's SqlRowSetMetaData interface. Used by ResultSetWrappingSqlRowSet.

  This implementation wraps a `javax.sql.ResultSetMetaData` instance, catching any SQLExceptions and translating them to the appropriate Spring DataAccessException.
