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) SEE ALSO

ExtUtils::Typemaps::Cmd - Quick commands for handling typemaps SYNOPSIS
From XS: INCLUDE_COMMAND: $^X -MExtUtils::Typemaps::Cmd -e "print embeddable_typemap(q{Excommunicated})" Loads "ExtUtils::Typemaps::Excommunicated", instantiates an object, and dumps it as an embeddable typemap for use directly in your XS file. DESCRIPTION
This is a helper module for ExtUtils::Typemaps for quick one-liners, specifically for inclusion of shared typemaps that live on CPAN into an XS file (see SYNOPSIS). For this reason, the following functions are exported by default: EXPORTED FUNCTIONS
embeddable_typemap Given a list of identifiers, "embeddable_typemap" tries to load typemaps from a file of the given name(s), or from a module that is an "ExtUtils::Typemaps" subclass. Returns a string representation of the merged typemaps that can be included verbatim into XS. Example: print embeddable_typemap( "Excommunicated", "ExtUtils::Typemaps::Basic", "./typemap" ); This will try to load a module "ExtUtils::Typemaps::Excommunicated" and use it as an "ExtUtils::Typemaps" subclass. If that fails, it'll try loading "Excommunicated" as a module, if that fails, it'll try to read a file called Excommunicated. It'll work similarly for the second argument, but the third will be loaded as a file first. After loading all typemap files or modules, it will merge them in the specified order and dump the result as an embeddable typemap. SEE ALSO
