我有一个枚举，我想从中获取一些信息。 这是枚举：
$parameters = array(
'filters' => 'ga:pagePath==/about'
'dimensions' => 'ga:pagePath',
'metrics' => 'ga:pageviews,ga:uniquePageviews',
'sort' => '-ga:pageviews'
);
$data = self::$analytics->data_ga->get(
'ga:100174927',
date("Y-m-d", $start),
date("Y-m-d", $finish),
'ga:visits',
$parameters
);
$analytics = array(
'pageviews' => 0,
'uniquePageviews' => 0
);
// This is the foreach loop that is creating the error:
foreach ($data->getRows() as $key => $row)
{
$analytics['pageviews'] += $row[1];
$analytics['uniquePageviews'] += $row[2];
}
return $analytics;
以下是一些代码，可以了解所有内容的含义：

我想每次都获得第四个号码。它必须采用这样的形式，但这不起作用：
private Prayer(double[] data, int prayerMask, boolean curse) {
this.id = (int) data[0];
this.level = (int) data[1];
this.config = (int) data[2];
this.drain = data[3] * 2;
this.icon = (int) (data.length == 5 ? data[4] : -1);
this.anim = data.length == 6 ? (int) data[4] : -1;
this.graphic = data.length == 6 ? (int) data[5] : -1;
this.name = Misc.formatPlayerName(this.toString());
this.prayMask = prayerMask;
this.curse = curse;
}
...
public double getDrain() {
return drain;
}
说明：我确实想要发生的是public void handlePrayerDrain() {
double toRemove = 0.0;
for (int j = 0; j < prayerData.length; j++) {
if (c.prayerActive[j]) {
toRemove += prayerData[j]/20;
}
}
if (toRemove > 0) {
toRemove /= (1 + (0.035 * c.playerBonus[11]));
}
c.prayerPoint -= toRemove;
if (c.prayerPoint <= 0) {
c.prayerPoint = 1.0 + c.prayerPoint;
reducePrayerLevel();
}
}
方法获取枚举的长度（handlePrayerDrain），之后它会检查哪一个（for (int j = 0; j < prayerData.length; j++) {）和之后，它检查排水量是多少（if (c.prayerActive[j]) {）
这是我的Client.java中的一些代码（如果这有帮助）：
toRemove += prayerData[j]/20;答案 0 :(得分：1)
如果要迭代枚举的所有可能值，请尝试：
for (Prayer p : Prayer.values()) {
// your logic goes here
}
答案 1 :(得分：0)
如果您使用的是Java 8，那么流提供了一种相当简洁的方法来汇总enum中的某些值。虽然要说明你想要做什么有点难以理解，但这里有一个类似的例子可能会给你你想要的东西（我想： - ））。
enum Prayer {
...
public double getCost();
}
class Player {
...
public boolean hasActivePrayer(Prayer prayer);
}
double toRemove = Arrays.stream(Prayer.values())
.filter(player.getActivePrayer()::contains)
.mapToDouble(Prayer::getDrain)
.sum() / 10;
...
