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

import com.fasterxml.jackson.databind.BeanProperty;
import com.fasterxml.jackson.databind.deser.ValueInstantiator;
import com.fasterxml.jackson.databind.PropertyValueBuffer;

public class MyClass {
    public static void main(String[] args) {
        ValueInstantiator valueInstantiator = // construct the appropriate value instantiator
        PropertyValueBuffer buffer = new PropertyValueBuffer(null, valueInstantiator.createFromObjectWith(null, null), 0);
        BeanProperty prop = // construct the appropriate BeanProperty
        Object value = // construct the appropriate value
        buffer.assignParameter(prop, value);
    }
}

In this example, an instance of ValueInstantiator is constructed to represent the value instantiator for the object, an instance of PropertyValueBuffer is constructed using the createFromObjectWith method of the ValueInstantiator class.

An instance of BeanProperty is constructed, and a value is constructed, these are passed to the assignParameter method of the buffer object.

The PropertyValueBuffer class is used to buffer property values during deserialization, it's used to keep track of property values and construct
