Class IntegerSyntax is an abstract base class providing the common implementation of all attributes with integer values. Under the hood, an integer attribute is just an integer. You can get an integer attribute's integer value by calling getValue(). An integer attribute's integer value is established when it is constructed (see IntegerSyntax(int)). Once constructed, an integer attribute's value is immutable.
