Subject: oeqa/core/decorator/__init__.py: set metaclass to ABCMeta
X-Git-Url: https://code.ossystems.io/gitweb?a=commitdiff_plain;h=8c3a8c5d9fb31edbc37d8239c4cf5312a815a344;p=openembedded-core.git

oeqa/core/decorator/__init__.py: set metaclass to ABCMeta

OETestFilter is a subclass of OETestDecorator. It wants to make
use of @abstractmethod decorator. But such decorator requires
metaclass to be ABCMeta to have effect. So add it now to achieve
the designed behaviour.

Comments from python's manual:
"""
Using this decorator requires that the class's metaclass is ABCMeta
or is derived from it.
"""
