      public class RowSetWarning
      extends SQLException

  An extension of `SQLException` that provides information about database warnings set on `RowSet` objects. Warnings are silently chained to the object whose method call caused it to be reported. This class complements the `SQLWarning` class.

  Rowset warnings may be retrieved from `JdbcRowSet`, `CachedRowSet`™, `WebRowSet`, `FilteredRowSet`, or `JoinRowSet` implementations. To retrieve the first warning reported on any `RowSet` implementation, use the method `getRowSetWarnings` defined in the `JdbcRowSet` interface or the `CachedRowSet` interface. To retrieve a warning chained to the first warning, use the `RowSetWarning` method `getNextWarning`. To retrieve subsequent warnings, call `getNextWarning` on each `RowSetWarning` object that is returned.

  The inherited methods `getMessage`, `getSQLState`, and `getErrorCode` retrieve information contained in a `RowSetWarning` object.

    - #### RowSetWarning

          public RowSetWarning​(String reason)

      Constructs a `RowSetWarning` object with the given value for the reason; SQLState defaults to null, and vendorCode defaults to 0.
      Parameters:
        `reason` - a `String` object giving a description of the warning; if the `String` is `null`, this constructor behaves like the default (zero parameter) `RowSetWarning` constructor

    - #### RowSetWarning

          public RowSetWarning()

      Constructs a default `RowSetWarning` object. The reason defaults to `null`, SQLState defaults to null and vendorCode defaults to 0.

    - #### RowSetWarning

          public RowSetWarning​(String reason,
                               String SQLState)

      Constructs a `RowSetWarning` object initialized with the given values for the reason and SQLState. The vendor code defaults to 0. If the `reason` or `SQLState` parameters are `null`, this constructor behaves like the default (zero parameter) `RowSetWarning` constructor.
      Parameters:
        `reason` - a `String` giving a description of the warning;
        `SQLState` - an XOPEN code identifying the warning; if a non standard XOPEN SQLState is supplied, no exception is thrown.

    - #### RowSetWarning

          public RowSetWarning​(String reason,
                               String SQLState,
                               int vendorCode)

      Constructs a fully specified `RowSetWarning` object initialized with the given values for the reason, SQLState and vendorCode. If the `reason`, or the `SQLState` parameters are `null`, this constructor behaves like the default (zero parameter) `RowSetWarning` constructor.
      Parameters:
        `reason` - a `String` giving a description of the warning;
        `SQLState` - an XOPEN code identifying the warning; if a non standard XOPEN SQLState is supplied, no exception is thrown.
        `vendorCode` - a database vendor-specific warning code

  - ### Method Detail

    - #### getNextWarning

          public RowSetWarning getNextWarning()

      Retrieves the warning chained to this `RowSetWarning` object.
      Returns:
        the `RowSetWarning` object chained to this one; if no `RowSetWarning` object is chained to this one, `null` is returned (default value)
      See Also:
        `setNextWarning(javax.sql.rowset.RowSetWarning)`

    - #### setNextWarning

          public void setNextWarning​(RowSetWarning warning)

      Sets warning as the next warning, that is, the warning chained to this `RowSetWarning` object.
      Parameters:
        `warning` - the `RowSetWarning` object to be set as the next warning; if the `RowSetWarning` is null, this represents the finish point in the warning chain
