Class HttpAsyncLink

java.lang.Object
  java.lang.Thread
      edu.nrao.widar.util.HttpAsyncLink

All Implemented Interfaces:

java.lang.Runnable

public class HttpAsyncLink
extends java.lang.Thread

A psuedo 'non-blocking' HTTP communciation Thread. HttpLink uses this Thread class to implement its asyncQuery methods. It initiates the comms in its own Thread and then fires a DataReadyEvent when it has the response. In this manner it behaves to the caller as non-blocking I/O.

This class will most likely always be used only by HttpLink but it is made public because there is no reason why it cannot be used stand-alone if someone desires.
