Signature de la fonction class_mapper

def class_mapper(class_, configure=True) 

Description

class_mapper.__doc__

Given a class, return the primary :class:`_orm.Mapper` associated
    with the key.

    Raises :exc:`.UnmappedClassError` if no mapping is configured
    on the given class, or :exc:`.ArgumentError` if a non-class
    object is passed.

    Equivalent functionality is available via the :func:`_sa.inspect`
    function as::

        inspect(some_mapped_class)

    Using the inspection system will raise
    :class:`sqlalchemy.exc.NoInspectionAvailable` if the class is not mapped.
