FallbackProxy #

FallbackProxy(*api_versions: Any)

Proxy object that provides transparent fallback across multiple API versions.

This class delegates attribute access to a sequence of API implementations. When a callable attribute is invoked and raises OpenMLNotSupportedError, the proxy automatically attempts the same method on subsequent API instances until one succeeds.

PARAMETER DESCRIPTION
*api_versions

One or more API implementation instances ordered by priority. The first API is treated as the primary implementation, and subsequent APIs are used as fallbacks.

TYPE: Any DEFAULT: ()

RAISES DESCRIPTION
ValueError

If no API implementations are provided.
Notes

Attribute lookup is performed dynamically via __getattr__. Only methods that raise OpenMLNotSupportedError trigger fallback behavior. Other exceptions are propagated immediately.
