QuaternaryPredicate
The
Class
of
Predicate
s that require four arguments.
Relationships
Parents
可繼承的關係
The class of
Relation
s whose properties can be inherited downward in the class hierarchy via the
subrelation
Predicate
.
Predicate
A
Predicate
is a sentence-forming
Relation
. Each tuple in the
Relation
is a finite, ordered sequence of objects. The fact that a particular tuple is an element of a
Predicate
is denoted by '(*predicate* arg_1 arg_2 .. arg_n)', where the arg_i are the objects so related. In the case of
BinaryPredicate
s, the fact can be read as `arg_1 is *predicate* arg_2' or `a *predicate* of arg_1 is arg_2'.
QuaternaryRelation
QuaternaryRelation
s relate four items. The two
subclass
es of
QuaternaryRelation
are
QuaternaryPredicate
and
TernaryFunction
.
