テーブルとインデックスに関する構造体
ちょっと整理。結構省略してる、結構というかほとんど。
struct st_myisam_info { MYISAM_SHARE *s; } MI_INFO; struct st_mi_isam_share { MI_KEYDEF *keyinfo; HA_KEYSEG *keyparts; } MYISAM_SHARE; struct st_mi_keydef { struct st_mi_isam_share *share; uint16 keysegs; HA_KEYSEG *seg, *end; } MI_KEYDEF; class ha_myisam: public handler { MI_INFO *file; } struct st_table { TABLE_SHARE *s; handler *file; KEY *key_info; Field **field; } TABLE; struct st_table_share { KEY *key_info; Field **field; } TABLE_SHARE; struct st_key { uint key_parts; KEY_PART_INFO *key_part; struct st_table *table; } KEY; struct st_key_part_info { Field *field; } KEY_PART_INFO; class handler :public Sql_alloc { protected struct st_table *table; const handlerton *ht; handler(const handlerton *ht_arg, TABLE *table_arg); }
