DataListHolder (spine 3.1.0 API)

java.lang.Object
- org.openmuc.jeebus.spine.spi.function.DataListHolder<DATA,SELECTOR>

Type Parameters:

DATA - The type of data elements in the list.
```
public class DataListHolder<DATA,SELECTOR>
extends java.lang.Object
```
Holder class that encapsulates access to the list of DATA objects used for ReadListFeatureFunction and ReadAndWriteListFeatureFunction. Implements many of the operations that just need to access the list and manipulate its data.
Methods on this class perform no validation or notification. However, they take functional interfaces as parameters, and/or return lists of notifications, so that the feature functions can hook in validation and notification properly.
