T
- The type of the object that the resolver produces.public interface EntityResolver<T>
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
String
s containing each customer name.
