angelos.lib.ioc¶

The Inversion of Control (IoC) framework is used as a central part of both the server and client. It is used to start application services and make them available in the whole application.

class angelos.lib.ioc.Config¶

Bases: object

Mixin for a Configuration class that might load and prepare the Container.

class angelos.lib.ioc.Container(config: dict = {})¶

Bases: object

The IoC Container class is responsible for initializing and globally enabling access to application services.

Parameters: config (dict) – The configuration being loaded into the IoC.

__config¶

Internal IoC configuration.

Type: dict

__instances¶

Instanced application services.

Type: dict

class angelos.lib.ioc.ContainerAware(ioc: angelos.lib.ioc.Container)¶

Bases: object

Mixin that makes its inheritors aware of the IoC container.

Parameters: ioc (Container) – The IoC Container.

__ioc¶

Internal reference to the IoC.

Type: type

property ioc¶

Makes the IoC container accessible publically.

Returns: The IoC container.
Return type: Container

class angelos.lib.ioc.Handle(_type: Any)¶

Bases: object

The Handle class allows application services to be instanciated at a later state, rather than on boot. This allows processes that are dependent on user input to make choises about services at runtime. The service in this handle can be set multiple times. Handle implements the Descriptor Protocol.

Parameters: _type (Any) – The service class type that should be put here.

__type¶

Internally the class type supported at runtime.

Type: Any

__value¶

Internally the instance of the application service class.

Type: Any

__name¶

Internally the name of the service.

Type: str

class angelos.lib.ioc.LogAware(ioc: angelos.lib.ioc.Container)¶

Bases: angelos.lib.ioc.ContainerAware

Mixin for log awareness, drop-in for ContainerAware.

CRITICAL = (41,)¶

NORMAL = (21,)¶

WARNING = (31,)¶

critical(msg, *args, **kwargs)¶: Log dangerous event.

log(msg, *args, **kwargs)¶: Log an event, not supposed to be used directly.

normal(msg, *args, **kwargs)¶: Log normal event.

warning(msg, *args, **kwargs)¶: Log suspicious event.

class angelos.lib.ioc.StaticHandle(_type: Any)¶

Bases: angelos.lib.ioc.Handle

The static handle works the same way as the Handle, except it can only be set once.
