public class BurlapInput
extends AbstractBurlapInput

Input stream for Burlap requests.

BurlapInput is unbuffered, so any client needs to provide its own buffering.

 InputStream is = ...; // from http connection
 BurlapInput in = new BurlapInput(is);
 String value;

 in.startReply();         // read reply header
 value = in.readString(); // read string value
 in.completeReply();      // read reply footer
