PPI::Token::Quote - String quote abstract base class
PPI::Token::Quote
isa PPI::Token
isa PPI::Element
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:
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).
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>
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.
See the support section in the main module.
