Package com.caucho.hessian.micro

Class MicroHessianInput

java.lang.Object
com.caucho.hessian.micro.MicroHessianInput
public class MicroHessianInput extends 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
