NAME
Specio::Exporter - Base class for type libraries
VERSION
version 0.48
SYNOPSIS
package MyApp::Type::Library;
use parent 'Specio::Exporter';
use Specio::Declare;
declare( ... );
# more types here
package MyApp::Foo;
use MyApp::Type::Library
DESCRIPTION
Inheriting from this package makes your package a type exporter. By
default, types defined in a package are never visible outside of the
package. When you inherit from this package, all the types you define
internally become available via exports.
The exported types are available through the importing package's "t"
subroutine.
By default, types your package imports are not re-exported:
package MyApp::Type::Library;
use parent 'Specio::Exporter';
use Specio::Declare;
use Specio::Library::Builtins;
In this case, the types provided by Specio::Library::Builtins are not
exported to packages which "use MyApp::Type::Library".
You can explicitly ask for types to be re-exported:
package MyApp::Type::Library;
use parent 'Specio::Exporter';
use Specio::Declare;
use Specio::Library::Builtins -reexport;
In this case, packages which "use MyApp::Type::Library" will get all
the types from Specio::Library::Builtins as well as any types defined
in "MyApp::Type::Library".
ADDITIONAL EXPORTS
If you want to export some additional subroutines from a package which
has "Specio::Exporter" as its parent, define a sub named
"_also_export". This sub should return a list of subroutines defined in
your package that should also be exported. These subs will be exported
unconditionally to any package that uses your package.
COMBINING LIBRARIES WITH Specio::Subs
You can combine loading libraries with subroutine generation using
Specio::Subs by using "_also_export" and
"Specio::Subs::subs_installed_into":
package My::Library;
use My::Library::Internal -reexport;
use Specio::Library::Builtins -reexport;
use Specio::Subs qw( My::Library::Internal Specio::Library::Builtins );
sub _also_export {
return Specio::Subs::subs_installed_into(__PACKAGE__);
}
