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.
