类 AbstractHessianInput

  • 直接已知子类:
    Hessian2Input, HessianInput
    public abstract class AbstractHessianInput
extends Object
    Abstract base class for Hessian requests. Hessian users should only need to use the methods in this class. 

     AbstractHessianInput in = ...; // get input
 String value;

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