PPI::Token::Attribute - A token for a subroutine attribute
PPI::Token::Attribute
isa PPI::Token
isa PPI::Element
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.
This class provides some additional methods beyond those provided by its PPI::Token and PPI::Element parent classes.
The "identifier" attribute returns the identifier part of the attribute.
That is, for the attribute "foo(bar)", the "identifier" method would return "foo".
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.
See the support section in the main module.
