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

A token for a subroutine attribute

## NAME

PPI::Token::Attribute - A token for a subroutine attribute

## INHERITANCE

```
  PPI::Token::Attribute
  isa PPI::Token
      isa PPI::Element
```

## DESCRIPTION

In Perl, attributes are a relatively recent addition to the language.

Given the code `" sub foo : bar(something) {} "`, the `bar(something)` part is the attribute.

A `"PPI::Token::Attribute"` token represents the entire of the attribute, as the braces and its contents are not parsed into the tree, and are treated by Perl (and thus by us) as a single string.

## METHODS

This class provides some additional methods beyond those provided by its PPI::Token and PPI::Element parent classes.

### identifier

The `"identifier"` attribute returns the identifier part of the attribute.

That is, for the attribute `foo(bar)`, the `"identifier"` method would return `"foo"`.

### parameters

The `"parameters"` method returns the parameter string for the attribute.

That is, for the attribute `foo(bar)`, the `"parameters"` method would return `"bar"`.

Returns the parameters as a string (including the null string `''` for the case of an attribute such as `foo()`.)

Returns `"undef"` if the attribute does not have parameters.

## SUPPORT

See the support section in the main module.
