Field Documentation

dfield_t* dtuple_t::fields


ulint dtuple_t::info_bits

info bits of an index record: the default is 0; this field is used if an index record is built from a data tuple

ulint dtuple_t::magic_n

magic number, used in debug assertions

ulint dtuple_t::n_fields

number of fields in dtuple

ulint dtuple_t::n_fields_cmp

number of fields which should be used in comparison services of rem0cmp.*; the index search is performed by comparing only these fields, others are ignored; the default value in dtuple creation is the same value as n_fields

ut_list_node< dtuple_t > dtuple_t::tuple_list

data tuples can be linked into a list using this field
