NAME

PPI::Token::Quote - String quote abstract base class

INHERITANCE

  PPI::Token::Quote
  isa PPI::Token
      isa PPI::Element

DESCRIPTION

The "PPI::Token::Quote" class is never instantiated, and simply provides a common abstract base class for the four quote classes. In a ``quote'' is limited to only the quote-like things that themselves directly represent a string. (although this includes double quotes with interpolated elements inside them).

The subclasses of "PPI::Token::Quote" are:

'' - PPI::Token::Quote::Single

q{} - PPI::Token::Quote::Literal

- PPI::Token::Quote::Double

qq{} - PPI::Token::Quote::Interpolate

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

Please note that although the here-doc does represent a literal string, it is such a nasty piece of work that in

it is given the honor of its own token class (PPI::Token::HereDoc).

METHODS

string

The "string" method is provided by all four ::Quote classes. It won't get you the actual literal Perl value, but it will strip off the wrapping of the quotes.

  # The following all return foo from the ->string method
  'foo'
  "foo"
  q{foo}
  qq <foo>

literal

The "literal" method is provided by ::Quote::Literal and ::Quote::Single. This returns the value of the string as Perl sees it: without the quote marks and with "\\" and "\'" resolved to "\" and "'".

The "literal" method is not implemented by ::Quote::Double or ::Quote::Interpolate yet.
