Creating catalog provider bundles
|
|
---------------------------------
|
|
|
|
``di.DeclarativeCatalog.Bundle`` is a limited collection of catalog providers.
|
|
While catalog could be used as a centralized place for particular providers
|
|
group, such bundles of catalog providers can be used for creating several
|
|
limited scopes that could be passed to different subsystems.
|
|
|
|
``di.DeclarativeCatalog.Bundle`` has exactly the same API as
|
|
``di.DeclarativeCatalog`` except of the limitations on getting providers.
|
|
|
|
Each ``di.DeclarativeCatalog`` has a reference to its bundle class -
|
|
``di.DeclarativeCatalog.Bundle``. For example, if some concrete catalog has name
|
|
``SomeCatalog``, then its bundle class could be reached as
|
|
``SomeCatalog.Bundle``.
|
|
|
|
``di.DeclarativeCatalog.Bundle`` expects to get the list of its catalog providers
|
|
as positional arguments and will limit the scope of created bundle to this
|
|
list.
