Here is an example of how to use the ObjectIdReader class in the com.fasterxml.jackson.databind package in Java:

import com.fasterxml.jackson.databind.JavaType;
import com.fasterxml.jackson.databind.ObjectIdGenerator;
import com.fasterxml.jackson.databind.PropertyName;
import com.fasterxml.jackson.databind.deser.ValueInstantiator;
import com.fasterxml.jackson.databind.introspect.AnnotatedMember;
import com.fasterxml.jackson.databind.introspect.AnnotatedMethod;
import com.fasterxml.jackson.databind.ObjectIdReader;

public class MyClass {

    public static void main(String[] args) {
        JavaType idType = // construct the appropriate type for the id
        ObjectIdGenerator idGen = // construct the appropriate id generator
        PropertyName propName = // construct the appropriate property name
        AnnotatedMethod idSetter = // construct the appropriate setter method
        ValueInstantiator valueInstantiator = // construct the appropriate value instantiator
        ObjectIdReader idReader = new ObjectIdReader(idType, propName.getSimpleName(), idGen,
                                                      idSetter, valueInstantiator);
    }
}

In this example, an instance of JavaType is constructed to represent the type of the id, an instance of ObjectIdGenerator is constructed to represent the id generator, an instance of PropertyName is constructed to represent the name of the property, an instance of AnnotatedMethod is constructed to represent the setter method for the id property, and an instance of ValueInstantiator is constructed to represent the value instantiator.

These are used to create an instance of ObjectIdReader using the constructor that takes JavaType, String, ObjectIdGenerator, AnnotatedMember, and ValueInstantiator as arguments.

The ObjectIdReader class is used to handle deserialization of Object Ids, it's commonly used when working with object references and deserializing object graphs.

Keep in mind that this is just an example, you can use ObjectIdReader class in different way based on your requirement and you may need to adapt the example to your specific use case.
