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.

   implementation_name
       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.
