j#NddlZddlmZddlmZGddej Zy)N)Optional)messagescreZdZdZej deejdeejfdZ y)MessagePreprocessorae Abstract base class for message preprocessing. This class provides a common interface for pre-processing messages, allowing derived classes to implement custom preprocessing logic tailored to specific requirements. Instances of this class cannot be created directly; it must be subclassed with the `preprocess` method implemented. messagereturncy)a Processes and preprocesses the given message to prepare it for further operations. This is an abstract method and needs to be implemented in any concrete subclass. The preprocessing step is typically used for transformations or checks on the given input message before further processing. Args: message: The input message to be preprocessed. This can optionally be None. Returns: The processed message after preprocessing. Returns None if the input message is None or if a message was fully consumed here and no further processing is required.
