Interface EntityResolver<T>

Type Parameters:

T - The type of the object that the resolver produces.

public interface EntityResolver<T>

An interface to perform client side projection on a retrieved entity. An EntityResolver instance must implement a resolve method projecting the entity data represented by the parameters passed in as a new instance of the type specified by the type parameter.

This interface is useful for converting directly from table entity data to a client object type without requiring a separate table entity class type that deserializes every property individually. For example, a client can perform a client side projection of a Customer entity by simply returning the String for the CustomerName property of each entity. The result of this projection will be a collection of Strings containing each customer name.

Method Summary
