Here is an example of how the com.fasterxml.jackson.databind.deser.std.AsDeductionTypeDeserializer class might be used:

import com.fasterxml.jackson.core.JsonParser;
import com.fasterxml.jackson.databind.DeserializationContext;
import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.deser.std.AsDeductionTypeDeserializer;
import com.fasterxml.jackson.databind.deser.std.StdDeserializer;

public class MyTypeDeserializer extends AsDeductionTypeDeserializer<MyType> {

    public MyTypeDeserializer() {
        super(MyType.class);
    }

    @Override
    protected MyType _deserialize(JsonParser p, DeserializationContext ctxt, JsonNode node) {
        // custom deserialization logic goes here
    }
}

This class allows you to define custom deserialization logic for the specified class. You should extend this class and override the _deserialize method to provide your own implementation of how to deserialize your class.
