Méthode sqlalchemy.TypeDecorator.literal_processor

Signature de la méthode literal_processor

def literal_processor(self, dialect) 

Description

literal_processor.__doc__

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

        Subclasses here will typically override
        :meth:`.TypeDecorator.process_literal_param` instead of this method
        directly.

        By default, this method makes use of
        :meth:`.TypeDecorator.process_bind_param` if that method is
        implemented, where :meth:`.TypeDecorator.process_literal_param` is
        not.  The rationale here is that :class:`.TypeDecorator` typically
        deals with Python conversions of data that are above the layer of
        database presentation.  With the value converted by
        :meth:`.TypeDecorator.process_bind_param`, the underlying type will
        then handle whether it needs to be presented to the DBAPI as a bound
        parameter or to the database as an inline SQL value.
