    • getSelectionColumnsList

      List<Integer> getSelectionColumnsList()
       Column selection in the table list selection
 For example, [0, 2, 4, 7] selects the index subscript of the column.
 If the length of the array is 0, it means not need to decode.

       Column selection in the table list selection
 For example, [0, 2, 4, 7] selects the index subscript of the column.
 If the length of the array is 0, it means not need to decode.
      repeated int32 selection_columns = 4;
      Returns:
      The count of selectionColumns.

    • getSelectionColumns

      int getSelectionColumns(int index)

 For example, [0, 2, 4, 7] selects the index subscript of the column.
 If the length of the array is 0, it means not need to decode.
      repeated int32 selection_columns = 4;
      Parameters:
      index - The index of the element to return.
      Returns:
      The selectionColumns at the given index.
