Overview:

Useful functions for processing python classes and types.

class_wraps

hbutils.reflection.clazz.class_wraps(wrapped: type, assigned: Tuple[str] = '__module__', '__name__', '__qualname__', '__doc__', '__annotations__', updated: Tuple[str] = ())

Overview:

Wrapper decorator for class.

Arguments:

• wrapped (type): Wrapped class.

• assigned (Tuple[str]): Wrapper assignments, equal to functools.wraps()’s

Examples:

>>> def cls_dec(clazz):
>>>     @class_wraps(clazz)
>>>     class _NewClazz(clazz):
>>>         pass
>>>
>>>     return _NewClazz

common_base

hbutils.reflection.clazz.common_base(cls: type, *clss: type) → type

Overview:

Get common base class of the given classes. Only __base__ is considered.

Arguments:

• cls (type): First class.

• clss (type): Other classes.

Returns:

• base (type): Common base class.

>>> from hbutils.reflection import common_base
>>> common_base(object)
<class 'object'>
>>> common_base(object, int, str)
