Creating catalog subsets
|
||
|
|
------------------------
|
||
|
|
|
||
|
|
``di.AbstractCatalog`` subset is a limited collection of catalog providers.
|
||
|
|
While catalog could be used as a centralized place for particular providers
|
||
|
|
group, such subsets of catalog providers can be used for creating several
|
||
|
|
limited scopes that could be passed to different subsystems.
|
||
|
|
|
||
|
|
``di.AbstractCatalog`` subsets could be created by instantiating of particular
|
||
|
|
catalog with passing provider names to the constructor.
|
||
|
|
|
||
|
|
Example:
