Detailed Description

Wrapper around POSIX extended 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

See also: The manpage regex(7) for more information about POSIX regular expressions. These differ somewhat from Perl and sed regular expressions.; Foam::regExp and Foam::regExpCxx

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

Deprecated:: This class will be superseded by Foam::regExpCxx as compiler support for regular expressions continues to improve.
