Class::C3::Componentised Load mix-ins or components to your C3-based class. package MyModule; use strict; use warnings; use base 'Class::C3::Componentised'; sub component_base_class { "MyModule::Component" } package main; MyModule->load_components( qw/Foo Bar/ ); # Will load MyModule::Component::Foo an MyModule::Component::Bar This will inject base classes to your module using the Class::C3 method resolution order. Please note: these are not plugins that can take precedence over methods declared in MyModule. If you want something like that, consider MooseX::Object::Pluggable.

load_components( @comps )
Loads the given components into the current module. If a module begins with a "+" character, it is taken to be a fully qualified class name, otherwise "$class->component_base_class" is prepended to it. Calling this will call "Class::C3::reinitialize".

load_own_components( @comps )
Simialr to load_components, but assumes every class is "$class::$comp".

load_optional_components
As load_components, but will silently ignore any components that cannot be found.

ensure_class_loaded
Given a class name, tests to see if it is already loaded or otherwise defined. If it is not yet loaded, the package is require'd, and an exception is thrown if the class is still not loaded. BUG: For some reason, packages with syntax errors are added to %INC on require =cut # # TODO: handle ->has_many('rel', 'Class'...) instead of # ->has_many('rel', 'Some::Schema::Class'...) # sub ensure_class_loaded { my ($class, $f_class) = @_; croak "Invalid class name $f_class" if ($f_class=~m/(?:\b:\b|\:{3,})/); return if Class::Inspector->loaded($f_class); eval "require $f_class"; # require needs a bareword or filename if ($@) { if ($class->can('throw_exception')) { $class->throw_exception($@); } else { croak $@; } } }

ensure_class_found
Returns true if the specified class is installed or already loaded, false otherwise

inject_base
Does the actual magic of adjusting @ISA on the target module. Matt S. Trout and the DBIx::Class team Pulled out into seperate module by Ash Berlin "<ash@cpan.org>" You may distribute this code under the same terms as Perl itself.
