treevalue.utils.clazz¶
class_wraps¶
-
treevalue.utils.clazz.class_wraps(original_class: Type[_ClassType])[source]¶ - Overview:
Wrap class like functools.wraps, can be used in class decorators.
- Arguments:
original_class (
Type[_ClassType]): Original class for wrapping.
- Example:
>>> def cls_dec(clazz): >>> @class_wraps(clazz) >>> class _NewClazz(clazz): >>> pass >>> >>> return _NewClazz
init_magic¶
-
treevalue.utils.clazz.init_magic(init_decorator)[source]¶ - Overview:
Magic for initialization function of a class.
- Arguments:
init_decorator (
Callable): Initialization function decorator.
- Example:
>>> from functools import wraps >>> >>> def _init_dec(func): >>> @wraps(func) >>> def _new_func(value): >>> func(value + 1) >>> >>> return _new_func >>> >>> @init_magic(_init_dec) >>> class Container: >>> def __init__(self, value): >>> self.__value = value >>> >>> @property >>> def value(self): >>> return self.__value >>> >>> c = Container(1) >>> c.value # 2 >>> c2 = Container(33) >>> c2.value # 34
common_bases¶
-
treevalue.utils.clazz.common_bases(*classes: Type, base: Optional[Union[Collection[Type], Type]] = None) → Set[Type][source]¶ - Overview:
Get all the common bases of the classes.
- Arguments:
classes (
Type): Target classes.base (
Union[Collection[Type], Type, None]): Limit of the base class, default is None which means no limit.
- Returns:
bases (
Set[Type]): A set of classes which is the common bases of the classes, only high leveled classes will be kept.
common_direct_base¶
-
treevalue.utils.clazz.common_direct_base(*classes: Type, base: Optional[Union[Collection[Type], Type]] = None)[source]¶ - Overview:
Get the common direct base of the classes.
- Arguments:
classes (
Type): Target classes.base (
Union[Collection[Type], Type, None]): Limit of the base class, default is None which means no limit.
- Returns:
base (
Type): A class which is all the bases.
