quantlab.core.component.config_cls_of#

quantlab.core.component.config_cls_of(cls)[source]#

Return the config class cls declares in config_cls.

The config class is never guessed. A guess could rebuild one factor backend’s config dict as another backend’s config, and it would let any importable callable be instantiated with a config dict.

Parameters:

clstype: The class to rebuild.

Returns:

type: Its config_cls.

Raises:

TypeError: If cls has no config_cls attribute, or it is not a type.

Examples

>>> from quantlab.label.forward import Forward
>>> config_cls_of(Forward).__name__
'ForwardConfig'
