class SpecialCaseList::Matcher

Declaration

class SpecialCaseList::Matcher { /* full declaration omitted */ };

Description

Represents a set of regular expressions. Regular expressions which are "literal" (i.e. no regex metacharacters) are stored in Strings. The reason for doing so is efficiency; StringMap is much faster at matching literal strings than Regex.
