所有已实现的接口:: Hessian2Constants

public class Hessian2Output
extends AbstractHessianOutput
implements Hessian2Constants

Output stream for Hessian 2 requests.

Since HessianOutput does not depend on any classes other than in the JDK, it can be extracted independently into a smaller package.

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

 OutputStream os = ...; // from http connection
 Hessian2Output out = new Hessian2Output(os);
 String value;

 out.startCall("hello", 1); // start hello call
 out.writeString("arg1");   // write a string argument
 out.completeCall();        // complete the call
