创建一个未知类型的数组

如果要具有未知类型的数组，请使用泛型：

 public <T> T[] getAttribArray(Class<T> repeatingGrpClass) {    //get the attribute based on the class (which you might get based on the enum for example)    return (T[]) getAttrib( repeatingGrpClass.getName() ); //note that you might want to use the class object instead of its name here }
