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



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 PPI, 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 PPI 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.

SUPPORT
       See the support section in the main module.
