Ice.Blobject

class Ice.Blobject

Bases: Object, ABC

Special-purpose servant base class that allows a subclass to handle synchronous Ice invocations as “blobs” of bytes.

This class serves as a base for creating servants that can process encoded Ice operation arguments and return results or exceptions in an encoded form. Subclasses must implement the ice_invoke method to handle the invocation logic.

abstractmethod ice_invoke(bytes: bytes, current: Current) → tuple[bool, bytes] | Awaitable[tuple[bool, bytes]]

Dispatches a synchronous Ice invocation.

The operation’s arguments are encoded in the bytes parameter. The return value must be a tuple of two values: the first is a boolean indicating whether the operation succeeded (True) or raised a user exception (False), and the second is the encoded form of the operation’s results or the user exception.

Parameters:

  • bytes (bytes) – The encoded operation arguments.

  • current (Ice.Current) – The current invocation context.

Returns:

  • bool True if the operation succeeded, False if it raised a user exception.

  • bytes The encoded form of the operation’s results or the user exception.

Return type:

tuple of (bool, bytes) or awaitable of tuple of (bool, bytes)
