Regular expressions

Regular expression operators are defined in validator/operators/regex.hpp header file.

regex_match

Contains regular expression. Operands can be either of boost::regex or to-string-convertible types.

regex_ncontains

Does not contain regular expression. Operands can be either of boost::regex or to-string-convertible types.

String patterns

Operators for checking some common string patterns are defined in validator/operators/number_patterns.hpp and validator/operators/string_patterns.hpp header files.

str_int

String can be converted to integer.

str_float
