bool isValid(std::string &Error) const
isValid - returns the error encountered during regex compilation, if any.
Definition: Regex.cpp:69
This is a 'vector' (really, a variable-sized array), optimized for the case when the array is small.

StringRef - Represent a constant reference to a string, i.e.
Definition: StringRef.h:50
