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.
sub foo : bar(something) {}
bar(something)
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.
PPI::Token::Attribute
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.
identifier
That is, for the attribute foo(bar), the identifier method would return "foo".
foo(bar)
"foo"
The parameters method returns the parameter string for the attribute.
parameters
That is, for the attribute foo(bar), the parameters method would return "bar".
"bar"
Returns the parameters as a string (including the null string '' for the case of an attribute such as foo().)
''
foo()
Returns undef if the attribute does not have parameters.
undef
