DataProxyHandler

public final class DataProxyHandler extends Object implements InvocationHandler
A simple {@link InvocationHandler} to act as the handler for our generated {@link java.lang.reflect.Proxy}-based entity instances.

This is a trivial impl which simply keeps the property values into a Map.
