=head1 NAME
PPI::Token::Quote - String quote abstract base class
=head1 INHERITANCE
PPI::Token::Quote
isa PPI::Token
isa PPI::Element
=head1 DESCRIPTION
The C<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 C<PPI::Token::Quote> are:
=over 2
=item C<''> - L<PPI::Token::Quote::Single>
=item C<q{}> - L<PPI::Token::Quote::Literal>
=item C<""> - L<PPI::Token::Quote::Double>
=item C<qq{}> - L<PPI::Token::Quote::Interpolate>
=back
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 B<does> represent a literal
string, it is such a nasty piece of work that in L<PPI> it is given the
honor of its own token class (L<PPI::Token::HereDoc>).

# PPI::Token::Quote Methods
=pod
=head2 string
The C<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>
=begin testing string 15
# Prove what we say in the ->string docs
my $Document = PPI::Document->new(\<<'END_PERL');
'foo'
"foo"
q{foo}
qq <foo>
END_PERL
isa_ok( $Document, 'PPI::Document' );
my $quotes = $Document->find('Token::Quote');
is( ref($quotes), 'ARRAY', 'Found quotes' );
is( scalar(@$quotes), 4, 'Found 4 quotes' );
foreach my $Quote ( @$quotes ) {
isa_ok( $Quote, 'PPI::Token::Quote');
can_ok( $Quote, 'string' );
is( $Quote->string, 'foo', '->string returns "foo" for '
. $Quote->content );
}
=end testing
=cut
#sub string {
# my $class = ref $_[0] || $_[0];
# die "$class does not implement method ->string";
#}
=pod
=head2 literal
The C<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 C<\\> and C<\'> resolved to C<\>
and C<'>.
The C<literal> method is not implemented by ::Quote::Double or
::Quote::Interpolate yet.
