framework3.base.base_clases.BasePlugin
¶
Bases: ABC
Base class for all plugins in the framework.
This abstract class provides core functionality for attribute management, serialization, and type checking. It serves as the foundation for all plugin types in the framework, ensuring consistent behavior and interfaces.
Key Features
- Automatic separation of public and private attributes
- Type checking for methods using typeguard
- Inheritance of type annotations from abstract methods
- JSON serialization and deserialization
- Rich representation for debugging
Usage
To create a new plugin type, inherit from this class and implement the required methods. For example:
Attributes:
Name | Type | Description |
---|---|---|
_public_attributes |
dict
|
A dictionary containing all public attributes of the plugin. |
_private_attributes |
dict
|
A dictionary containing all private attributes of the plugin. |
Methods:
Name | Description |
---|---|
__new__ |
Creates a new instance of the plugin and applies type checking. |
__init__ |
Initializes the plugin instance, separating public and private attributes. |
model_dump |
Returns a copy of the public attributes. |
dict |
Alias for model_dump. |
json |
Returns a JSON-encodable representation of the public attributes. |
item_dump |
Returns a dictionary representation of the plugin, including its class name and parameters. |
get_extra |
Returns a copy of the private attributes. |
model_validate |
Validates and creates an instance from a dictionary. |
Note
This class uses the ABC (Abstract Base Class) to define an interface that all plugins must adhere to. It also leverages Python's type hinting and the typeguard library for runtime type checking.
