Interface CommandListener

  • All Known Subinterfaces:
    CommandResultListener
    public interface CommandListener

    Defines the interface that you should implement to receive information on the result of a command.

    For more about commands, see CommandSubscription.

    A trivial implementation would be as follows :

    import java.util.HashMap;
import java.util.Map;

import com.caplin.streamlink.CommandErrorEvent;
import com.caplin.streamlink.CommandListener;
import com.caplin.streamlink.StreamLink;

public class CommandListenerSnippet
{
        
        public CommandListenerSnippet(StreamLink streamLink)
        {
                Map fieldData = new HashMap();
                fieldData.put("fieldName", "fieldValue");
                
                streamLink.publishToSubject("/SUBJECT", fieldData, new CommandListener() {
                        
                        public void onCommandOk(String subject) {
                                System.out.println("Publish to " + subject + " Succesful");
                        }
                        
                        public void onCommandError(String subject, CommandErrorEvent commandErrorEvent) {
                                System.out.println("Publish Error : " + commandErrorEvent.getError());
                        }
                        
                });
                
        }
        
}
