Définition

class Composite(CompositeProperty, _DeclarativeMapped):

help(Composite)

Declarative-compatible front-end for the :class:`.CompositeProperty`
class.

Public constructor is the :func:`_orm.composite` function.

.. versionchanged:: 2.0 Added :class:`_orm.Composite` as a Declarative
   compatible subclass of :class:`_orm.CompositeProperty`.

.. seealso::

    :ref:`mapper_composite`
