aliased::factory - shorter versions of a class tree's constructors
use aliased::factory YAPI => 'Yahoo::Marketing'; my $service = YAPI->KeywordResearchService->new(...); my $res = $service->getRelatedKeywords( relatedKeywordRequest => YAPI->RelatedKeywordRequestType->new(...) );
This package is similar to aliased, but performs on-demand loading for packages below the shortened 'root package'. For example, the above code will automatically load the KeywordResearchService and RelatedKeywordRequestType packages from the Yahoo::Marketing:: hierarchy.
To load a second-level package:
use aliased::factory BAR => 'Foo::Bar'; my $bort = BAR->Baz->Bort->new(...);
This would load the Foo::Bar::Baz and then Foo::Bar::Baz::Bort packages. Each method call require()s the corresponding package and returns an aliased::factory object, which has a new() method (see below.)
Returns a new object of the class represented by the $factory object.
my $instantiated = $factory->new(...);
The class being instantiated must have a new() method.
The rest of this is functionality used to create the factory.
Installs a sub 'shortname' in your package containing an object pointed at $package.
aliased::factory->import(shortname => $package);
When called on a factory object, attempts to require the subpackage. If this succeeds, it will return a coderef (which will return the subfactory when executed.)
my $coderef = $factory->can('subpackage');
This method is used by AUTOLOAD().
Attempts to load the $factory's corresponding subpackage, returns a the subfactory object or throws a fatal error: "Can't locate ... in @INC ...".
my $subfactory = $factory->subpackage;
