java.lang.Objectcom.caucho.hessian.io.AbstractHessianOutput
com.caucho.hessian.io.HessianOutput
Output stream for Hessian requests, compatible with microedition Java. It only uses classes and types available in JDK.
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 HessianOutput out = new HessianOutput(os); String value; out.startCall("hello"); // start hello call out.writeString("arg1"); // write a string argument out.completeCall(); // complete the call
