    * Describes a Nukkit plugin. *

    * 在jar格式的插件中,插件的描述内容可以在plugin.yml中定义。比如这个:
    * The description of a jar-packed plugin can be defined in the 'plugin.yml' file. For example: *

     * name: HelloWorldPlugin
     * main: com.cnblogs.xtypr.helloworldplugin.HelloWorldPlugin
     * version: "1.0.0"
     * api: ["1.0.0"]
     * load: POSTWORLD
     * author: 粉鞋大妈
     * description: A simple Hello World plugin for Nukkit
     * website: http://www.cnblogs.com/xtypr
     * permissions:
     *  helloworldplugin.command.helloworld:
     *   description: Allows to use helloworld command.
     *   default: true
     * commands:
     *  helloworld:
     *   description: the helloworld command
     *   usage: "/helloworld"
     *   permission: helloworldplugin.command.helloworld
     * depend:
     * - TestPlugin1
     * 
    * 在使用plugin.yml来定义插件时,{@code name}、{@code main}、{@code version}、{@code api}这几个字段是必需的, * 要让Nukkit能够正常加载你的插件,必须要合理地填写这几个字段。
    * When using plugin.yml file to define your plugin, it's REQUIRED to fill these items: * {@code name},{@code main},{@code version} and {@code api}.You are supposed to fill these items to make sure * your plugin can be normally loaded by Nukkit.
    * *

    接下来对所有的字段做一些说明,加粗的字段表示必需,斜体表示可选:(来自 * 粉鞋大妈的博客文章

    一个插件完整的名字由{@code 名字+" v"+版本号}组成。比如:

    *

    {@code HelloWorld v1.0.0}

    插件的信息前缀在记录器记录信息时,会作为信息头衔使用。如果没有定义记录器,会使用插件的名字作为信息头衔。
    * When a PluginLogger logs, the message title is used as the prefix of message. If prefix is undefined, * the plugin name will be used instead.

    * * @return 这个插件的作信息前缀。如果没定义,返回{@code null}。

    * The names of the plugins what is depended by this plugin. *

    * Nukkit插件的依赖有这些注意事项:
    Here are some note for Nukkit plugin depending: *

      *
    • 一个插件不能依赖自己(否则会报错)。
      A plugin can not depend on itself (or there will be an exception).
    • *
    • 如果一个插件依赖另一个插件,那么必须要安装依赖的插件后才能加载这个插件。
      * If a plugin relies on another one, the another one must be installed at the same time, or Nukkit * won't load this plugin.
    • *
    • 当一个插件所依赖的插件不存在时,Nukkit不会加载这个插件,但是会提醒用户去安装所依赖的插件。
      * When the required dependency plugin does not exists, Nukkit won't load this plugin, but will tell the * user that this dependency is required.
    • *
    * *

    举个例子,如果A插件依赖于B插件,在没有安装B插件而安装A插件的情况下,Nukkit会阻止A插件的加载。 * 只有在安装B插件前安装了它所依赖的A插件,Nukkit才会允许加载B插件。
    * For example, there is a Plugin A which relies on Plugin B. If you installed A without installing B, * Nukkit won't load A because its dependency B is lost. Only when B is installed, A will be loaded * by Nukkit.

    * * @return 插件名字列表的 {@code List}对象。
    A {@code List} object carries the plugin names. * @see PluginDescription * @since Nukkit 1.0 | Nukkit API 1.0.0 */ public List getDepend() { return depend; } /** * 返回这个插件的描述文字。
    * Returns the description text of this plugin. * * @return 这个插件的描述文字。
    The description text of this plugin. * @see PluginDescription * @since Nukkit 1.0 | Nukkit API 1.0.0 */ public String getDescription() { return description; } /** * TODO finish javadoc */ public List getLoadBefore() { return loadBefore; } /** * 返回这个插件的主类名。
    * Returns the main class name of this plugin. * *

    一个插件的加载都是从主类开始的。主类的名字在插件的配置文件中定义后可以通过这个函数返回。一个返回值例子:
    * The load action of a Nukkit plugin begins from main class. The name of main class should be defined * in the plugin configuration, and it can be returned by this function. An example for return value:
    * {@code "com.example.ExamplePlugin"}

    * * @return 这个插件的主类名。
    The main class name of this plugin. * @see PluginDescription * @since Nukkit 1.0 | Nukkit API 1.0.0 */ public String getMain() { return main; } /** * 返回这个插件的名字。
