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.

SUPPORT

See the support section in the main module.
