Add Type_handler::val_int_signed_typecast() and Type_handler::val_int_unsigned_typecast()

    XMLWordPrintable

    Details

      Description

      The code in these methods:

      longlong Item::val_int_unsigned_typecast();
      longlong Item::val_int_signed_typecast();
      

      is not friendly to pluggable data types, as it tests for cmp_type().
      Pluggable data types may want to implement a different way for signed/unsigned conversion.

      Under terms of this task will add new methods in Type_handler:

      virtual longlong Item_val_int_signed_typecast(Item *item) const;
      virtual longlong Item_val_int_unsigned_typecast(Item *item) const;
      

      and split the mentioned code into virtual implementations for relevant Type_handler_xxx classes.
