public class Predicate extends TypedStructureAdapter
A general predicate which contains an identifier that describes its meaning, an argument count referred as arity and a list of sorts defining the types for the arguments of the predicate. Sub classes might forbid some of the general features to form a predicate which fits another language. Force the arity to be zero gives an propositional predicate for example.
