Bug:621861 Changed C structs to C++ class in the following files: filesort.cc, filesort_info.h, sql_sort.h, table.h. removed the '_st' from the name of some of the classes. For more detail of changes made read the merge proposal notes. |

The structure sort_addon_field describes a fixed layout

for field values appended to sorted values in records to be sorted
|
42 |
in the sort buffer.

Only fixed layout is supported now.

themselves. Offsets are from the last sorted field, that is from the
|
46 |
record referefence, which is still last component of sorted records.
|
|

It is preserved for backward compatiblility.

in the sort buffer. It is used also when these values are read

from a temporary file/buffer. As the reading procedures are beyond the

51 |
scope of the 'filesort' code the values have to be retrieved via
|

52 |
the callback function 'unpack_addon_fields'.
