Méthode sqlalchemy.TypeDecorator.bind_processor

Signature de la méthode bind_processor

def bind_processor(self, dialect) 

Description

bind_processor.__doc__

Provide a bound value processing function for the
        given :class:`.Dialect`.

        This is the method that fulfills the :class:`.TypeEngine`
        contract for bound value conversion.   :class:`.TypeDecorator`
        will wrap a user-defined implementation of
        :meth:`process_bind_param` here.

        User-defined code can override this method directly,
        though its likely best to use :meth:`process_bind_param` so that
        the processing provided by ``self.impl`` is maintained.

        :param dialect: Dialect instance in use.

        This method is the reverse counterpart to the
        :meth:`result_processor` method of this class.
