PPI::Token::Attribute(3)

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.
