=head1 Building Containers
+=head2 build_component_subcontainer
+
+Container that stores all components, i.e. all models, views and controllers
+together. Each service is an instance of the actual component, and by default
+it lives while the application is running. Retrieving components from this
+subcontainer will instantiate the component, if it hasn't been instantiated
+already, but will not execute ACCEPT_CONTEXT.
+
=head2 build_model_subcontainer
-Container that stores all models.
+Container that stores references for all models that are inside the components
+subcontainer. Retrieving a model triggers ACCEPT_CONTEXT, if it exists.
=head2 build_view_subcontainer
-Container that stores all views.
+Same as L<build_model_subcontainer>, but for views.
=head2 build_controller_subcontainer
-Container that stores all controllers.
+Same as L<build_model_subcontainer>, but for controllers. The difference is
+that there is no ACCEPT_CONTEXT for controllers.
=head1 Building Services
The parameter list is split on comma (C<,>). You can override this method to
do your own string munging, or you can define your own macros in
-C<MyApp-E<gt>config-E<gt>{ 'Plugin::ConfigLoader' }-E<gt>{ substitutions }>.
+C<< <MyApp->config( 'Plugin::ConfigLoader' => { substitutions => { ... } } ) >>.
Example:
- MyApp->config->{ 'Plugin::ConfigLoader' }->{ substitutions } = {
- baz => sub { my $c = shift; qux( @_ ); }
- }
+ MyApp->config( 'Plugin::ConfigLoader' => {
+ substitutions => {
+ baz => sub { my $c = shift; qux( @_ ); },
+ },
+ });
The above will respond to C<__baz(x,y)__> in config strings.
