Twitter4j が提供するコード例を使用して、1,000 個のステータスのリストが収集された後にストリームを停止し、このリストを返したいと思います。どうやってやるの?
public class Stream {
public List<Status> execute throws TwitterException {
List<Status> statuses = new ArrayList();
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true);
cb.setOAuthConsumerKey("bbb");
cb.setOAuthConsumerSecret("bbb");
cb.setOAuthAccessToken("bbb");
cb.setOAuthAccessTokenSecret("bbb");
TwitterStream twitterStream = new TwitterStreamFactory(cb.build()).getInstance();
StatusListener listener = new StatusListener() {
public void onStatus(Status status) {
statuses.add(status);
if (statuses.size>1000){
//return statuses. Obviously that's not the correct place for a return statement...
}
}
public void onDeletionNotice(StatusDeletionNotice statusDeletionNotice) {
System.out.println("Got a status deletion notice id:" + statusDeletionNotice.getStatusId());
}
public void onTrackLimitationNotice(int numberOfLimitedStatuses) {
System.out.println("Got track limitation notice:" + numberOfLimitedStatuses);
}
public void onScrubGeo(long userId, long upToStatusId) {
System.out.println("Got scrub_geo event userId:" + userId + " upToStatusId:" + upToStatusId);
}
public void onException(Exception ex) {
ex.printStackTrace();
}
};
FilterQuery fq = new FilterQuery();
String keywords[] = {"Keyword 1", "Keyword 2"};
fq.track(keywords);
twitterStream.addListener(listener);
twitterStream.filter(fq);
}
