What are some advanced examples of serializers in programming?

Advanced serializers can include custom serializers for complex data types, such as nested objects or polymorphic types.

Can you give me an example of a custom serializer?

Sure! For instance, in Python, you can create a custom JSON serializer by subclassing json.JSONEncoder to handle specific data types.

How would that look in code?

Here's a simple example:

import json

class CustomSerializer(json.JSONEncoder):
    def default(self, obj):
        if isinstance(obj, MyCustomClass):
            return {'custom_field': obj.custom_value}
        return super().default(obj)

What about deserializing with custom logic?

For deserialization, you can define a custom method to convert JSON back into your object, often using a factory method.
