If object supposed to have a type, then no, Ada packages have no types.

Node = graph. Node type is scalar. You can allocate it, have arrays of,
whatever you like keeping in mind that it is an access type.
Compare it to Ada task or file types. You can allocate tasks, you can
have arrays of tasks, but remember that these are only proxy objects to
some other entities.

That depends on the use case you have in mind.
