Class ODataResponse

java.lang.Object

org.apache.olingo.odata2.api.processor.ODataResponse

public abstract class ODataResponse
extends Object

An ODataResponse is usually created by an ODataProcessor during request handling.

The handler can use a serializer to create an OData body (== response entity) and can set various response headers. A response can be created using the builder pattern:

 ODataResponse response = ODataResponse.entity("hello world").setStatus(HttpStatusCodes.OK).build();
