Field Documentation

struct Instance* RelationInstance::parent[2]

relations can have only two parents and normally they only have one. They have two only during an ARE_THE_SAME

struct TypeDescription* RelationInstance::desc

holds the child list stuff

unsigned long RelationInstance::tmp_num

used when an instance tree is being copied

unsigned int RelationInstance::anon_flags

anonymous field to be manipulated

enum Expr_enum RelationInstance::type

what kind of the 5 possible types of reln type should be down in union RelationUnion

struct relation* RelationInstance::ptr

pointer to an instance relation

struct gl_list_t* RelationInstance::whens

link to whens on which the rel appears

struct gl_list_t* RelationInstance::logrels

link to satified's on which rel appears
