All Implemented Interfaces:
  `Serializable, Iterable<Throwable>`

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.

- ## Constructor Details

  - ### 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.

    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.
