free(+Ref) is det

Delete object if it exists.

 send(+Object, +Selector, +Arg...) is semidet

Succeeds if sending a message to Object with Selector and the given Arguments succeeds. Normally, goal_expansion/2 expands all these goals into send(Receiver, Method(Args...)).

 get(+Object, :Selector, +Arg..., ?Rval) is semidet

See the comments with send/[3-12].

 send_implementation(+Id, +Message, +Object)[multifile]

Method-bodies are compiled into clauses for this predicate. Id is a unique identifier for the implementation, Message is a compound whose functor is the method name and whose arguments are the arguments to the method-call. Object is the receiving object.

 get_implementation(+Id, +Message, +Object, -Return)[multifile]

As send_implementation/3, but for get-methods.
