#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, note that String::InterpolatedVariables allows to extract 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.
