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

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.
