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.

Got any ideas for methods? Submit a report to rt.cpan.org!

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 strong 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.
