Specifications: (class)pure

public normal_behavior
ensures \result <==> (* elem tests as "==" to one of the objects in the set *);

has

Is the argument ".equals" to one of the values in the set.

See Also:

has(Object)

Specifications: (class)pure

public normal_behavior
ensures \result <==> (* elem tests as ".equals" to one of the objects in the set *);
