Class MicroHessianInput

  • public class MicroHessianInput
extends java.lang.Object
    Input stream for Hessian requests, compatible with microedition Java. It only uses classes and types available to J2ME. In particular, it does not have any support for the <double> type.

    MicroHessianInput does not depend on any classes other than in J2ME, so it can be extracted independently into a smaller package.

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

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

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