All Known Implementing Classes:: RequiredDefaultStateValues

public interface DefaultStateValues

Implementing classes of this interface can be used to define default values for states.

This interface enables ModificationsBuilder instances to transform an Mdib into a modifications set in which every generated state visits a callback function of the implementing class.

For each state type that is supposed to have a default value, a class derived from DefaultStateValues is recognized by a ModificationsBuilder if it contains functions of the following pattern:

 void onFoo(AbstractMetricState state) {
     // modify any abstract metric state type here
     // NumericMetricState is not affected as there is another callback defined
 }
 void onBar(NumericMetricState state) {
     // Every NumericMetricState goes to this callback
 }

The first method is called for each passed AbstractMetricState. Please note that this function is not called in case there is a method declaration with a type that derives from AbstractMetricState. In that case the method needs to call the more generated callback itself. The second method is called for each NumericMetricState.
