Question

我尝试检查名为interLinks和intraLinks的Priority Queuue结构中的两种链接。根据下面的URLremoveCondition()方法，如果我interLinks intraLinks，我会尝试从PQueue删除所有这两种网址链接MaxWaitTime和10 Seconds将其设置为URLremoveCondition()该方法将删除这些链接。

但问题是方法interLinks仅从PQueue中删除intraLinks而不删除interLinks。如何解决此问题以删除intraLinks和URLremoveCondition()？

这是我的方法public static PriorityQueue <LinkNodeLight> PQueue = new PriorityQueue <> (); private static Integer MaxWaitTime = new Integer (10000); // 10 Seconds public void URLremoveCondition() { synchronized (PQueue) { Iterator<LinkNodeLight> iterator = PQueue.iterator(); while(iterator.hasNext()){ LinkNodeLight URL = iterator.next(); long URLWaitingTime = System.currentTimeMillis() - URL.enqueTime.getMillis(); if(URLWaitingTime > MaxWaitTime){ iterator.remove(); System.out.println("DELETED NODE: " + URL.url + " WAITTIME: " + Long.toString(URLWaitingTime)); } } } }

LinkNodeLight

这是我的班级import org.joda.time.DateTime; public class LinkNodeLight implements Comparable<LinkNodeLight> { protected String url; protected float weight; protected DateTime enqueTime; protected boolean interLinks; public String getUrl() { return url; } public float getWeight() { return weight; } public void setWeight(float weight) { this.weight = weight; } public DateTime getEnqueTime() { return enqueTime; } public LinkNodeLight(String url) { this.url = url; } public boolean isInterLinks() { return interLinks; } public void setInterLinks(boolean interLinks) { this.interLinks = interLinks; } public void setEnqueTime(DateTime enqueTime) { this.enqueTime = enqueTime; } @Override public int compareTo(LinkNodeLight link) { if (this.weight < link.weight) return 1; else if (this.weight > link.weight) return -1; return 0; } }：

interLinks

修改

我在这里创建intraLinks和import java.util.LinkedList; import java.util.List; public class URLWeight { public static List<LinkNodeLight> weight(LinkNode sourceLink, List<LinkNodeLight> links) { List<LinkNodeLight> interLinks = new LinkedList<>(); List<LinkNodeLight> intraLinks = new LinkedList<>(); for (LinkNodeLight link : links) { if (isIntraLink(sourceLink, link)) { intraLinks.add(link); link.setInterLinks(false); } else { interLinks.add(link); link.setInterLinks(true); } }

<?php

// connects to the DB
include ('connectdb.php');

//query that gets the "trade_id" from the table with all the trades, where the "open_time" is older than 30 days, "close_price" is NULL.
$result = $db->query("SELECT trade_id FROM trades WHERE open_time < (NOW() - INTERVAL 30 DAYS) AND close_price IS NULL");
// create an array
$rows = array();
// loop through the table and drop the data into the array
while($row = $result->fetch(PDO::FETCH_ASSOC)){
    $rows[] = $row;    
}       

$count = count($rows);
$i = 0;
//loops through the table
while($i < $count){
//updates the table "orders" where the unique_ID matches the trade_ID, and will change the column "notified" to -1
    $update = $db->prepare("UPDATE orders SET notified=? WHERE unique_id=$rows[$i]");
    $update->execute(array(-1));
//updates the table "trades" where the trade_ID matches the trade_ID, and will change the column "close_price" to -1
    $update2 = $db->prepare("UPDATE trades SET close_price=? WHERE trade_id=$rows[$i]");
    $update2->execute(array(-1));
    $i++;
}   
// Closes connection
$db = null;

我通过为getter生成setter intraLinks到LinkNodeLight类来解决问题

protected boolean intraLinks;

public boolean isIntraLinks() {
    return intraLinks;
}

public void setInterLinks(boolean interLinks) {
    this.interLinks = interLinks;
}


public void setIntraLinks(boolean intraLinks) {
    this.intraLinks = intraLinks;
}

根据某些条件从PriorityQueue中删除不同类型的项目
