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 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.
