Put the specified constraint on the value of the described option, replacing any constraint that had been in effect (if any). The behavior is undefined unless the described option is not a flag and the balcl::OptionValue type of the described option corresponds to the type of constraint. Note that two distinct objects that have the same constraint put on them will compare unequal unless the constraint is shared among them, which can be done by: ` aTypeInfo.setConstraint(anotherTypeInfo.constraint()); `
