Interface JsonBeanReader<T>

public interface JsonBeanReader<T>
Provides a JSON reader that can hold a persistence context and load context while reading JSON.

This provides a mechanism such that an object loaded from JSON can have unique instances by using a persistence context and also support further lazy loading (via a load context).
