NAME
       ExtUtils::Typemaps::OutputMap - Entry in the OUTPUT section of a typemap

SYNOPSIS
	 use ExtUtils::Typemaps;
	 ...
	 my $output = $typemap->get_output_map('T_NV');
	 my $code = $output->code();
	 $output->code("...");

DESCRIPTION
       Refer to ExtUtils::Typemaps for details.

METHODS
   new
       Requires "xstype" and "code" parameters.

   code
       Returns or sets the OUTPUT mapping code for this entry.

   xstype
       Returns the name of the XS type of the OUTPUT map.

   cleaned_code
       Returns a cleaned-up copy of the code to which certain transformations have been applied to make it more ANSI compliant.

   targetable
       This is an obscure optimization that used to live in "ExtUtils::ParseXS" directly.

       In a nutshell, this will check whether the output code involves calling "set_iv", "set_uv", "set_nv", "set_pv" or "set_pvn" to set the
       special $arg placeholder to a new value AT THE END OF THE OUTPUT CODE. If that is the case, the code is eligible for using the
       "TARG"-related macros to optimize this.	Thus the name of the method: "targetable".

       If the optimization can not be applied, this returns undef.  If it can be applied, this method returns a hash reference containing the
       following information:

	 type:	    Any of the characters i, u, n, p
	 with_size: Bool indicating whether this is the sv_setpvn variant
	 what:	    The code that actually evaluates to the output scalar
	 what_size: If "with_size", this has the string length (as code,
		    not constant)
