Detailed Description

Wrapper around C++11 regular expressions with some additional prefix-handling. The prefix-handling is loosely oriented on PCRE regular expressions and provides a simple means of tuning the expressions.

The prefixes are detected as (?...) at the beginning of the regular expression. Any unknown/unsupported prefixes are silently ignored.

"(?!i)" : one or more embedded pattern-match modifiers for the entire pattern.
the 'i' indicates ignore-case
the '!' (exclamation) indicates negated (inverted) matching

Note: Uses either POSIX extended regular expressions or modified ECMAScript regular expression grammar

Since ECMAScript grammar may not work correctly on all installations, the current default is to use extended regular expressions.

The C++11 regular expressions may be broken on some compilers. For example, gcc 4.8 is known to fail. For these systems the POSIX implementation or alternative must be used.

Warning: This class should not be used directly. Use the Foam::regExp typedef instead.
