% load the example:

| ?- logtalk_load(serialization(loader)). ... yes

% create a protocol declaring some predicates:

| ?- create_protocol(abc, [], [public([a/1,b/1,c/1])]).

yes

% create some dynamic objects implementing the protocol:

| ?- create_object(Object1, [implements(abc)], [], [a(1),b(1),c(1)]), create_object(Object2, [implements(abc)], [], [a(2),b(2),c(2)]), create_object(Object3, [implements(abc)], [], [a(3),b(3),c(3)]).

Object1 = o1, Object2 = o2 Object3 = o3 yes

% save the objects to a file:

| ?- serializer::save(abc, abc_objects).

yes

% abolish all objects:

| ?- forall(conforms_to_protocol(Object,abc), abolish_object(Object)).

yes

% restore the serialized objects from the file:

| ?- serializer::restore(abc_objects).

yes

% confirm the restoring process worked as expected:

| ?- conforms_to_protocol(Object, abc), Object::(a(A), b(B), c(C)).

Object = o3, A = B, B = C, C = 1 ; Object = o4, A = B, B = C, C = 2 ; Object = o5, A = B, B = C, C = 3 yes
