所有已实现的接口:: Hessian2Constants

public class Hessian2Input
extends AbstractHessianInput
implements Hessian2Constants

Input stream for Hessian requests.

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

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

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