val is_in_idb : Predicate.predicate -> program -> bool

is_in_idb pred prog returns true if the predicate pred is an intensional predicate for the program prog

val is_head : Predicate.predicate -> Rule.rule -> bool

is_head pred rule returns true if the predicate pred matches with the head of the rule rule

val match_rules : Predicate.predicate -> program -> Rule.Rules.t

match_rules pred prog returns the set of rules of program prog whose heads match with pred

val get_rule_by_id : program -> int -> Rule.Rules.elt

get_rule_by_id program id Get the rule matching the id
