Modeling Configuration in Interface Style

To model a managed object that has configuration, implement the supplemental interface com.tibco.tea.agent.api.WithConfig<CONFIG>. WithConfig is a generic interface. It requires that you implement one method, getConfig, which returns a configuration object.

Prerequisites

The container object is defined in interface style.

Procedure

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.
    ...
}
```
Implement the WithConfig<CONFIG> interface in your managed object type. Substitute your configuration class as the generic type parameter CONFIG.
```
public class Radio implements TopLevelTeaObject, WithConfig<RadioConfig> {
    ...
    public RadioConfig getConfig() {
        ...
    }
}
```

Declare that the getConfig method returns an instance of your configuration class.

public class Radio implements TopLevelTeaObject, WithConfig<RadioConfig> {
    ...
    public RadioConfig getConfig() {
        ...
    }
}
