) |
Flatten associative operators at parse time.
This function flattens AND and OR operators at parse time if applicable, otherwise it creates new Item_cond_and or Item_cond_or respectively.
Template parameter Class
is Item_cond_and
or Item_cond_or
Template parameter Tag
is COND_AND_FUNC
(for Item_cond_and
) or COND_OR_FUNC
otherwise
mem_root | MEM_ROOT |
pos | parse location |
left | left argument of the operator |
right | right argument of the operator |

inline |
To * item_cond_cast | ( | Item *const | from | ) |
Helper function to imitate dynamic_cast for Item_cond hierarchy.
Template parameter To
is the destination type (Item_cond_and
etc.) Template parameter Tag
is the Functype tag to compare from->functype() with
from | source item |
