Python ensure_intersection_type Examples

Example #1

def get_intersection_type(
    types: Iterable[s_types.Type],
    *,
    ctx: context.ContextLevel,
) -> s_types.Type:

    ctx.env.schema, intersection, created = s_utils.ensure_intersection_type(
        ctx.env.schema, types)

    if created:
        ctx.env.created_schema_objects.add(intersection)
    elif (intersection not in ctx.env.created_schema_objects
          and intersection.get_name(ctx.env.schema).module != '__derived__'):
        ctx.env.schema_refs.add(intersection)

    return intersection

Example #2

def get_intersection_type(
    types: Iterable[s_types.Type],
    *,
    ctx: context.ContextLevel,
) -> s_types.Type:

    ctx.env.schema, intersection, created = s_utils.ensure_intersection_type(
        ctx.env.schema, types)

    if created:
        ctx.env.created_schema_objects.add(intersection)
    elif (intersection not in ctx.env.created_schema_objects and
          (not isinstance(intersection, s_obj.QualifiedObject)
           or intersection.get_name(ctx.env.schema).module != '__derived__')):
        ctx.env.add_schema_ref(intersection, expr=None)

    return intersection
