[英]java twitter4j are tweet ids unique
Doing some java dev with twitter4j and curious to know if when I make a call to 用twitter4j做一些java开发,好奇地想知道何时我打电话给
Status tweet = blah blah blah.
long tweetID = tweet.getId(); //Is this unique?
I setup a HashSet in order to keep track of tweets I've already received and I have a print statement for duplicates. 我设置一个HashSet来跟踪已经收到的推文,并且有一份打印声明以备重复。 I was under the impression that Twitter used a 64bit long to generate unique keys but I was unable to find any correlation between the twitter4j tweet id and Twitter's tweet id.
我的印象是,Twitter使用64位长来生成唯一密钥,但是我无法找到twitter4j tweet ID与Twitter的tweet ID之间的任何关联。 Main question is: Are the twitter4j Status tweet ids unique?
主要问题是:twitter4j状态推特ID是否唯一?
[Edit] Some elaboration, I have a HashSet of Longs 详细说明,我有一个HashSet的Longs
HashSet<Long> usedIds = new HashSet<Long>();
//Get new twitter4j Status
if(!usedIds.contains(tweetID)) {
//this is not a duplicate
//Place id into set
usedIds.add(tweetID);
//do work
} else {
//This is duplicate and my program is printing stuff
//From what I've learned this condition should never be met but it is
}
I'm fairly certain the twitter4j's Status.getId()
returns the unique ID of the Tweet, as determined by Twitter. 我相当确定twitter4j的
Status.getId()
返回Twitter所确定的Tweet的唯一ID。 It's not creating it's own IDs. 它不是在创建自己的ID。 Perhaps your HashSet is too aggressive with the key space and you're getting a collision, but the
getId
call is going to give you the Tweet's actual ID. 也许您的HashSet在密钥空间上过于激进,您会遇到冲突,但是
getId
调用将为您提供Tweet的实际ID。
