=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.
=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.
$name is a regexp, it returns an array of matching components. Otherwise, it
looks for the component with name $name.
-=head2 get_components_names_types
-
-Gets all components from all containers and returns them as an array of
-arrayrefs containing the component name and the component type (i.e., whether
-it's an instance or a class).
-
=head2 get_all_components
Fetches all the components, in each of the sub_containers model, view and
Searches for components in all containers. If $component is the full class
name, the subcontainer is guessed, and it gets the searched component in there.
Otherwise, it looks for a component with that name in all subcontainers. If
-$component is a regexp, it calls the method below, find_component_regexp,
-and matches all components against that regexp.
-
-=head2 find_component_regexp
-
-Finds components that match a given regexp. Used internally, by find_component.
+$component is a regexp it calls _find_component_regexp and matches all
+components against that regexp.
