PPI::Token::Regexp(3)                User Contributed Perl Documentation               PPI::Token::Regexp(3)



NAME
       PPI::Token::Regexp - Regular expression abstract base class

INHERITANCE
         PPI::Token::Regexp
         isa PPI::Token
             isa PPI::Element

DESCRIPTION
       The "PPI::Token::Regexp" class is never instantiated, and simply provides a common abstract base
       class for the three regular expression classes. These being:

       m// - PPI::Token::Regexp::Match
       s/// - PPI::Token::Regexp::Substitute
       tr/// - PPI::Token::Regexp::Transliterate

       The names are hopefully obvious enough not to have to explain what each class is. See their pages for
       more details.

       To save some confusion, it's worth pointing out here that "qr//" is not a regular expression (which
       PPI takes to mean something that will actually examine or modify a string), but rather a quote-like
       operator that acts as a constructor for compiled Regexp objects.

METHODS
       The following methods are inherited by this class' offspring:

   get_match_string
       The "get_match_string" method returns the portion of the regexp that performs the match.

   get_substitute_string
       The "get_substitute_string" method returns the portion of the regexp that is substituted for the
       match, if any.  If the regexp does not substitute, "undef" is returned.

   get_modifiers
       The "get_modifiers" method returns the modifiers of the regexp.

   get_delimiters
       The "get_delimiters" method returns the delimiters of the regexp as an array. The first element is
       the delimiters of the match string, and the second element (if any) is the delimiters of the
       substitute string (if any).

SUPPORT
       See the support section in the main module.
