Jython HashMap参数

Question

我正在使用PyPluginLoader为jython中的Minecraft服务器编写bukkit插件。我有事件和所有其他工作，但我想制作切换命令，它将打开blockspawn模式，但如果你再次输入它，它会关闭它。这是代码，错误如下：

from java.io import File
import org.bukkit as bukkit
server = bukkit.Bukkit.getServer()
log = server.getLogger()
Material = bukkit.Material
from org.bukkit.event import player
from org.bukkit.entity import EntityType
import org.bukkit.permissions
from org.bukkit.plugin.java import JavaPlugin
from org.bukkit import Server
from org.bukkit import plugin
from java.util import Date, HashSet, HashMap

z = HashMap


@hook.command("blockspawn", usage="/<command>",
                desc="Toggles blockspawning mode on/off")
def onbrix(sender, command, label):
    if z.containsKey(player):
      z.remove(player.getName())
      sender.sendMessage("Blockspawning OFF")
    else:
        z.put(player.getName())
        sender.sendMessage("Blockspawning ON")

ERROR：

Caused by: Traceback (most recent call last):
  File "<iostream>", line 23, in onbrix
TypeError: containsKey(): expected 2 args; got 1

Answer 1

我认为您的代码应为：

z = HashMap()

请注意括号。否则，您不会创建HashMap的实例。
