    - #### receivedRow

          public void receivedRow(FbStatement sender,
                                  RowValue rowValue)

      Description copied from interface: `StatementListener`
      Method to be notified of a new row of data.
      Specified by:
        `receivedRow` in interface `StatementListener`
      Parameters:
        `sender` - The `FbStatement` that called this method.
        `rowValue` - The row values.

    - #### allRowsFetched

          public void allRowsFetched(FbStatement sender)

      Description copied from interface: `StatementListener`
      Method to be notified when all rows have been fetched.

      This method may also be called when the statement did not produce any rows (or did not open a result set).

      Specified by:
        `allRowsFetched` in interface `StatementListener`
      Parameters:
        `sender` - The `FbStatement` that called this method.
      See Also:
        `StatementListener.statementExecuted(FbStatement, boolean, boolean)`

    - #### statementExecuted

          public void statementExecuted(FbStatement sender,
                                        boolean hasResultSet,
                                        boolean hasSingletonResult)

      Description copied from interface: `StatementListener`
      Method to be notified when a statement has been executed.

      This event with `hasResultSet=true` can be seen as the counter part of `StatementListener.allRowsFetched(FbStatement)`.

      Specified by:
        `statementExecuted` in interface `StatementListener`
      Parameters:
        `sender` - The `FbStatement` that called this method.
        `hasResultSet` - `true` there is a result set, `false` there is no result set
        `hasSingletonResult` - `true` singleton result, `false` statement will produce indeterminate number of rows; can be ignored when `hasResultSet` is false.

    - #### statementStateChanged

          public void statementStateChanged(FbStatement sender,
                                            StatementState newState,
                                            StatementState previousState)

      Description copied from interface: `StatementListener`
      Method to be notified when the state of a statement has changed.
      Specified by:
        `statementStateChanged` in interface `StatementListener`
      Parameters:
        `sender` - The `FbStatement` that called this method.
        `newState` - The new state of the statement
        `previousState` - The old state of the statement

    - #### warningReceived

          public void warningReceived(FbStatement sender,
                                      java.sql.SQLWarning warning)

      Description copied from interface: `StatementListener`
      Called when a warning was received for the `sender` statement.
      Specified by:
        `warningReceived` in interface `StatementListener`
      Parameters:
        `sender` - Statement receiving the warning
        `warning` - Warning

    - #### sqlCounts

          public void sqlCounts(FbStatement sender,
                                SqlCountHolder sqlCounts)

      Description copied from interface: `StatementListener`
      Called when the SQL counts of a statement have been retrieved.
      Specified by:
        `sqlCounts` in interface `StatementListener`
