I guess you want to know if the k-th dimension is unconstrained.
The easiest thing is to test whether the line whose direction is the k-th dimension is subsumed. Kind regards,

An even easier approach is to use method "constrains":
bool constrains(Variable var) const;
or better, since you are interested in the Java interface:
public native boolean constrains(Variable var);
