The :func:`_sa.inspect` function is the entry point to SQLAlchemy's public API for viewing the configuration and construction of in-memory objects. Depending on the type of object passed to :func:`_sa.inspect`, the return value will either be a related object which provides a known interface, or in many cases it will return the object itself. The rationale for :func:`_sa.inspect` is twofold. One is that it replaces the need to be aware of a large variety of "information getting" functions in SQLAlchemy, such as :meth:`_reflection.Inspector.from_engine`, :func:`.orm.attributes.instance_state`, :func:`_orm.class_mapper`, and others. The other is that the return value of :func:`_sa.inspect` is guaranteed to obey a documented API, thus allowing third party tools which build on top of SQLAlchemy configurations to be constructed in a forwards-compatible way. � )�exc)�utilTc �� � t | � � }|j D ]/}|t v r$t | }|du r| c S || � � }|� n�0dx}}|r|�|�t j d|z � � �|S )a� Produce an inspection object for the given target. The returned value in some cases may be the same object as the one given, such as if a :class:`_orm.Mapper` object is passed. In other cases, it will be an instance of the registered inspection type for the given object, such as if an :class:`_engine.Engine` is passed, an :class:`_reflection.Inspector` object is returned. :param subject: the subject to be inspected. :param raiseerr: When ``True``, if the given subject does not correspond to a known SQLAlchemy inspected type, :class:`sqlalchemy.exc.NoInspectionAvailable` is raised.
