Tzeva Adom API

Java library that communicates with Pikud Ha'oref and notifies registered listeners as soon as a Tzeva Adom happens.
Integrating it in projects(games, etc) used by many israelis, increases the chances of saving someone's life.

How to use

How to stop your addicting game on Tzeva Adom:

Game game = ...;

TzevaAdomNotifier notifier = new TzevaAdomNotifier.Builder()
        .onFailedRequest(exception -> LOGGER.error("Failed to request the latest alert from Pikud Haoref", exception))
        .onTzevaAdom(alert ->
        {
                game.stop();
                game.displayMessage("There is a Tzeva Adom in: " + alert.getRegion());
        })
        .build();

//this returns a CompletableFuture - so you can join() if your program needs to stay silent until a Tzeva Adom happens
notifier.listenAsync();

By saving the notifier object, you can receive the captured alert history:

import java.util.concurrent.TimeUnit;
import dte.tzevaadomapi.alert.Alert;

...
notifier.listenAsync();

//sleep for a day
TimeUnit.DAYS.sleep(1);

//print all the alerts from the last day
for(Alert alert : notifier.getHistory()) 
{
        LOGGER.warn("Alert at {} was in {}", alert.getRegion(), alert.getDate());
}

//check a specific region's alerts
List<Alert> telAvivAlerts = notifier.getHistory().ofRegion("תל אביב");

Adjustments

• Override the frequency of Tzeva Adom checks:

  new TzevaAdomNotifier.Builder()
  	.requestEvery(Duration.ofSeconds(3))

• Change the endpoint of Pikud Ha'oref if it was changed:

  //PHOAlertSource is the default AlertSource implementation, you can also implement your own.
  PHOAlertSource alertSource = new PHOAlertSource();
  alertSource.changeRequestURL(new URL("..."));
  
  new TzevaAdomNotifier.Builder()
  	.requestFrom(alertSource)

• Prevent console spam when handling exceptions:

  //LimitedExceptionHandler is a wrapper of Consumer<Exception> that stops handling after X times
  new TzevaAdomNotifier.Builder()
  	.onFailedRequest(new LimitedExceptionHandler(3, yourExceptionHandler));
