NAME

ExtUtils::XSpp::Node::Argument - Node representing a method/function argument

DESCRIPTION

An ExtUtils::XSpp::Node subclass representing a single function or method argument such as

  int foo = 0.

which would translate to an "ExtUtils::XSpp::Node::Argument" which has its "type" set to "int", its "name" set to "foo" and its "default" set to 0..

METHODS

new

Creates a new "ExtUtils::XSpp::Node::Argument".

Named parameters: "type" indicating the C++ argument type, "name" indicating the variable name, and optionally "default" indicating the default value of the argument.

uses_length

Returns true if the argument uses the XS length feature, false otherwise.

Returns the same as the "name" method unless the argument is of the "%length(something)" variant. In that case, "implementation_name" returns a munged version of the name that addresses the name mangling done by xsubpp: "XSauto_length_of_somthing".

fix_name_in_code

Given a code string, replaces any occurrances of the name of this "Argument" with its implementation name. If the implementation name is the same as the name, which is the most likely case, the code remains completely untouched.

Returns the potentially modified code.

ACCESSORS

type

Returns the type of the argument.

name

Returns the variable name of the argument variable.

default

Returns the default for the function parameter if any.

has_default

Returns whether there is a default for the function parameter.

function

Returns a reference to the containing function/method.

index

Returns the 0-based index of the argument in the argument list.
