SAReferenceTypeDecorator

class SAReferenceTypeDecorator(*args: Any, **kwargs: Any)

Bases: TypeDecorator

A SQLAlchemy type decorator for a curies.Reference.

Construct a TypeDecorator.

Arguments sent here are passed to the constructor of the class assigned to the impl class level attribute, assuming the impl is a callable, and the resulting object is assigned to the self.impl instance attribute (thus overriding the class attribute of the same name).

If the class level impl is not a callable (the unusual case), it will be assigned to the same instance attribute ‘as-is’, ignoring those arguments passed to the constructor.

Subclasses can override this to customize the generation of self.impl entirely.
