// TYPES
typedef unsigned result_type;
// Alias for the type of the values returned by this class.
// CLASS METHODS
static BSLS_KEYWORD_CONSTEXPR unsigned min();
// Return 0, the smallest value returned by 'operator()'.
static BSLS_KEYWORD_CONSTEXPR unsigned max();
// Return the largest value *potentially* returned by 'operator()'.
// The C++ standard requires that this returned value be greater
// than the value returned by the 'min' method; consequentally,
// this method returns 1 even though 'operator()(void)' always
// returns 0.
// CREATORS
//! SimpleUniformRandomNumberGenerator() = default;
// Create an 'SimpleUniformRandomNumberGenerator' object.
//! ~SimpleUniformRandomNumberGenerator() = default;
// Destroy this 'SimpleUniformRandomNumberGenerator' object.
// ACCESSORS
unsigned operator()(void) const;
// Return the next value from this 'SimpleUniformNumberGenerator'
// object. For this generator, that value is always 0.
