All the predicates in this section call a predicate on all members of
a list or until the predicate called fails. The predicate is called via
apply/2,
which implies common arguments can be put in front of the arguments
obtained from the list(s). For example:
?- maplist(plus(1), [0, 1, 2], X).
X = [1, 2, 3]
we will phrase this as ``Predicate is applied on ... ''
- checklist(+Pred, +List)
-
Pred is applied successively on each element of List
until the end of the list or Pred fails. In the latter case
the
checklist/2
fails.
- maplist(+Pred, ?List1,
?List2)
-
Apply Pred on all successive pairs of elements from List1
and List2. Fails if Pred can not be applied to a
pair. See the example above.
- sublist(+Pred, +List1,
?List2)
-
Unify List2 with a list of all elements of List1
to which
Pred applies.
