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

See also Configuration Aspect.

Prerequisites

The object is defined in interface style.

Procedure

  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() {
        ...
    }
