Class AdditionalSelectorConditions

java.lang.Object

org.openmuc.jeebus.spine.spi.AdditionalSelectorConditions

public class AdditionalSelectorConditions
extends java.lang.Object

Registry class for AdditionalSelectorCondition. Any new selector types with a condition other than Objects.equals(java.lang.Object, java.lang.Object) should be added to this class' static initializer.

This supersedes the previous mechanism where AdditionalSelectorConditions needed to be explicitly added by each use case. Reverting to the previous mechanism may prove necessary if a selector type is found which requires different conditions for different use cases. To help detect such a case should it occur, register(Class, Class, AdditionalSelectorCondition) will throw an error if multiple conditions are registered for the same type.

Currently registered selector and data types are:

• TimestampIntervalType selected by TimestampIntervalType
• PowerSequencePriceDataType selected by PowerSequencePriceListDataSelectorsType
• IncentiveDataType selected by IncentiveListDataSelectorsType
