Nice! How does it act when hitting 64bit integer overflows?
Sorry, lost among all the emails.
So, there are two ways to read integers with Tokenizer (after bug 1188983):
- via Next or Check
- via ReadInteger
The first two return a Token with uint64_t AsInteger() method if it fits
uint64_t. Otherwise the type of the token is TOKEN_ERROR.
The *templated* bool ReadInteger(T* result) does a runtime check whether
the parsed number fits the result type. If not, returns false, if yes,
sets the result value to your int and forwards the cursor.
And one more note: Tokenizer doesn't automatically recognize negative
numbers.
