|
// This class is a handy way to match a series of values to stings and vice
|
|
// versa. It should be initalized as static like an array, for example:
|
|
//
|
|
// const tokenset_t<int> tokens[] = {
|
|
// { "token1", 1 },
|
|
// { "token2", 2 },
|
|
// { "token3", 3 },
|
|
// { NULL, -1 }
|
|
// };
|
|
//
|
|
// Then you can call the operators on it by using:
|
|
//
|
|
// int t = tokens->GetToken( s );
|
|
//
|
|
// If s is "token1" it returns 1, etc. Invalid string returns the last NULL
|
|
// value. GetNameByToken() returns "__UNKNOWN__" when passed a mismatched
|
|
// token. GetNameByToken() returns szMismatchResult when passed a mismatched
|
|
// token and a string to return in case of mismatch.
|
|
