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.
