类 MicroBurlapOutput

java.lang.Object
  com.caucho.burlap.client.MicroBurlapOutput

public class MicroBurlapOutput
extends java.lang.Object

Output stream for Burlap 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.

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

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

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

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

构造方法摘要

MicroBurlapOutput()

MicroBurlapOutput(java.io.OutputStream os)
