# PPI::Token::Quote(3pm)

String quote abstract base class

## 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.
