Interface ThresholdEvaluatorState

All Superinterfaces:

ReinitializableState

All Known Implementing Classes:

AbstractThresholdEvaluatorState, ThresholdEvaluatorAbsoluteChange.ThresholdEvaluatorStateAbsoluteChange, ThresholdEvaluatorHighLow.ThresholdEvaluatorStateHighLow, ThresholdEvaluatorRearmingAbsoluteChange.ThresholdEvaluatorStateRearmingAbsoluteChange, ThresholdEvaluatorRelativeChange.ThresholdEvaluatorStateRelativeChange

public interface ThresholdEvaluatorState
extends ReinitializableState

Provides a method to evaluate a threshold and do basic population of events. There is an instance of ThresholdEvaluatorState for each configured thresholding type on each configured data source on each configured node/interface/etc.. The object that implements this interface usually also stores state (hence the name).
