Modeling Configuration in Annotation Style

To model a managed object that has configuration, implement a method that returns a configuration object, and annotate that method as @TeaGetConfig

1. Define a configuration bean that encapsulates all the parameters of the managed object. For example, the configuration of a radio could include changeable settings (such as the frequency and volume) and unchanging attributes (such as model and serial number).

   public class RadioConfig {
   
       private long frequency;
       private int volume;
       private string model;
       private string serial;
   
       // Constructors.  Get and set methods for each field.
       ...
   }

2. Define a method that gets the current configuration, returning it as an instance of your configuration class.

       public RadioConfig getConfig() {
           ...
       }
   

3. Annotate that method as @TeaGetConfig.

   @TeaGetConfig
       public RadioConfig getConfig() {
           ...
       }
