First, I define a group interface, in addition to inheriting the user's approach, GetUsers, getSubGroup. Code is shown later. Users must set their roles and groups in addition to a variety of different properties. .
Then define an AbstractGroup, he inherits the Group and AbstractUser and implements two methods defined by the Group interface. Users can inherit the AbstractGroup to handle the properties you want to define according to the implementation situation. (Because users of each system will have Different attributes, so keep abstract classes for users their own extensions). As long as initialization variables Description, Name, Group, ID, Prop, Role, PropMap, Subgroup, User.
Finally, a class XMLGroup is defined to implement a Group for a Group for a Group for general users. It is not recommended to use XMLGroup directly, because later versions may overwrite the class. If you want to use, you can rename it You can.
This part involves a resourcelib class, which is in the class that I defined by the storage of various resource configurations, which can be used directly.
