public interface Response

HTTP response.

Response interface is an abstraction of a HTTP response, that consists of a few headers and a body. To construct a response, use one of the composable decorators from org.takes.rs package. For example, this code will create a response with HTML inside:

 final Response response = new RsWithHeader(
   new RsWithBody(
     new RsWithStatus(200),
     "hello, world!"
   ),
   "Content-Type", "text/html"
 );

The implementations of this interface may require that head() method has to be invoked before reading from the InputStream obtained from the body() method, but they must NOT require that the InputStream has to be read from before the head() method invocation.

All implementations of this interface must be immutable and thread-safe.
