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).

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 it's 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>

SUPPORT

See the support section in the main module
