Detailed Description

requires (sizeof...(char_ranges_tp) % 2 == 0)
class mysql::gtids::detail::Char_table< Transform_tp, char_ranges_tp >

Helper class to hold lookup tables indexed by ascii characters.

Template Parameters

Transform_tp	Function that transforms letters. It should accept a char argument and return the type of values stored in the table.
char_ranges_tp	An even number of char constants, each pair defining the beginning and end of a range of characters included in the table. Both beginning and end are inclusive.
