PPI::Token::Regexp - Regular expression abstract base class
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
The following methods are inherited by this class' offspring:
The "get_match_string" method returns the portion of the regexp that performs the match.
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.
The "get_modifiers" method returns the modifiers of the regexp.
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).
