23 * A template base class for all enum types.
24 * This enum type exists to associate an enum value with a string for
25 * display/debug purposes.
26 * Concrete enum types use the CRTP. Derived classes thus inherit this
27 * base's function, but are not polymorphic.
34 * convert to string format for debug purposes
36 const std::string& to_string() const { return (m_desc); }
41 bool operator==(const enum_base& e) const { return (e.m_value == m_value); }
46 enum_base& operator=(const enum_base& e)
57 bool operator!=(const enum_base& e) const { return (e.m_value != m_value); }
60 * integer conversion operator
62 operator int() const { return (m_value); }
65 * Return the value of the enum - same as integer conversion
67 int value() const { return (m_value); }
71 * Constructor of an enum - takes value and string description
73 enum_base(int value, const std::string desc)
82 virtual ~enum_base() {}
86 * Integer value of the enum
