    • advanceNext

      public boolean advanceNext()
      Description copied from interface: RowIterator
      Advance this iterator by a single row. Returns `false` if this iterator has no more rows and `true` otherwise. If this returns `true`, then the new row can be retrieved by calling RowIterator.getRow().
      Specified by:
      advanceNext in interface RowIterator<org.apache.flink.table.data.binary.BinaryRowData>

    • getRow

      public org.apache.flink.table.data.binary.BinaryRowData getRow()
      Description copied from interface: RowIterator
      Retrieve the row from this iterator. This method is idempotent. It is illegal to call this method after [[advanceNext()]] has returned `false`.
      Specified by:
      getRow in interface RowIterator<org.apache.flink.table.data.binary.BinaryRowData>
