.IX Header "DESCRIPTION"
The \f(CW\*(C`PPI::Token::Quote\*(C'\fR class is never instantiated, and simply
provides a common abstract base class for the four quote classes.
In \s-1PPI,\s0 a \*(L"quote\*(R" 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).
.PP
The subclasses of \f(CW\*(C`PPI::Token::Quote\*(C'\fR are:
.ie n .IP "\*(Aq\*(Aq \- PPI::Token::Quote::Single" 2
.el .IP "\f(CW\*(Aq\*(Aq\fR \- PPI::Token::Quote::Single" 2
.IX Item " - PPI::Token::Quote::Single"
.PD 0
.ie n .IP """q{}"" \- PPI::Token::Quote::Literal" 2
.el .IP "\f(CWq{}\fR \- PPI::Token::Quote::Literal" 2
.IX Item "q{} - PPI::Token::Quote::Literal"
.ie n .IP """"" \- PPI::Token::Quote::Double" 2
.el .IP "\f(CW``''\fR \- PPI::Token::Quote::Double" 2
.IX Item """"" - PPI::Token::Quote::Double"
.ie n .IP """qq{}"" \- PPI::Token::Quote::Interpolate" 2
.el .IP "\f(CWqq{}\fR \- PPI::Token::Quote::Interpolate" 2
.IX Item "qq{} - PPI::Token::Quote::Interpolate"
.PD
.PP
The names are hopefully obvious enough not to have to explain what
each class is here. See their respective pages for more details.
.PP
Please note that although the here-doc \fBdoes\fR represent a literal
string, it is such a nasty piece of work that in \s-1PPI\s0 it is given the
honor of its own token class (PPI::Token::HereDoc).
.SH "METHODS"

.SS "string"
.IX Subsection "string"
The \f(CW\*(C`string\*(C'\fR 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.
.PP
.Vb 5
\&  # The following all return foo from the \->string method
\&  \*(Aqfoo\*(Aq
\&  "foo"
\&  q{foo}
\&  qq <foo>
.Ve
.SS "literal"
.IX Subsection "literal"
The \f(CW\*(C`literal\*(C'\fR 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 \f(CW\*(C`\e\e\*(C'\fR and \f(CW\*(C`\e\*(Aq\*(C'\fR resolved to \f(CW\*(C`\e\*(C'\fR
and \f(CW\*(C`\*(Aq\*(C'\fR.
.PP
The \f(CW\*(C`literal\*(C'\fR method is not implemented by ::Quote::Double or
::Quote::Interpolate yet.
