(Abstract base class. No instances are created.)

Class RWTRegexTraits<T> defines static, inline methods for returning specific RE character values. These values must be defined and include

• each of the regular expression special characters

• numeric and hex digits

• some escape sequences

In addition, any class used as a traits class must define some special methods for converting and comparing characters.

None

typedef char Char;
typedef int IntType;

None

NOTE -- All methods must be defined in a regular expression character traits class.

static inline void 
assign(char& x, const char& y);

Defines how to assign x the value of y.

static inline bool 
eq(const char& x, const char& y);

Returns true or false for (x == y).

Defines how to compare x and y for equality.

static inline bool 
lt(const char& x, const char& y);

Returns true or false for (x < y).

Defines how to determine if x is less than y.
