Advanced usage
==============
Current section of documentation describes advanced usage of
*Dependency Injector*.
@inject decorator
-----------------
``@inject`` decorator can be used for making *inline* dependency injections.
It *patches* decorated callable in such way that dependency injection will be
done during every call of decorated callable.
``@inject`` decorator takes only argument that is supposed to be an
``dependency_injector.injections.KwArg`` injection.
Any Python object will be injected *as is*, except *Dependency Injector*
providers, that will be called to provide injectable value.
Example:
.. literalinclude:: ../../examples/advanced_usage/inject_decorator_simple.py
:language: python
Example of dependecy injection in Flask view:
.. literalinclude:: ../../examples/advanced_usage/inject_decorator_flask.py
:language: python
