getPluginFilters

Pattern[] getPluginFilters()

返回这个插件加载器支持的文件类型。
Returns the file types this plugin loader supports.

在Nukkit读取所有插件时，插件管理器会查找所有已经安装的插件加载器，通过识别这个插件是否满足下面的条件， 来选择对应的插件加载器。
When Nukkit is trying to load all its plugins, the plugin manager will look for all installed plugin loader, and choose the correct one by checking if this plugin matches the filters given below.

举个例子，识别这个文件是否以jar为扩展名，它的正则表达式是：
For example, to check if this file is has a "jar" extension, the regular expression should be:
^.+\\.jar$
所以只读取jar扩展名的插件加载器，这个函数应该写成：
So, for a jar-extension-only file plugin loader, this method should be:

            @Override
      public Pattern[] getPluginFilters() {
          return new Pattern[]{Pattern.compile("^.+\\.jar$")};
      }
 

Returns:

表达这个插件加载器支持的文件类型的正则表达式数组。
An array of regular expressions, that describes what kind of file this plugin loader supports.
