Constant Field Values

fst

public static final org.nustaq.serialization.FSTConfiguration fst

state

protected T extends org.opennms.netmgt.threshd.AbstractThresholdEvaluatorState.AbstractState state

thresholdingSession

protected final ThresholdingSession thresholdingSession

Method Detail

initializeState

protected abstract void initializeState()

markDirty

protected void markDirty()

Marks the state for this evaluator as dirty. When a state is dirty it will be persisted the next time persistStateIfNeeded() is called.

Any operation that alters the state enough that it would affect threshold evaluation should call this method to mark the state dirty.

evaluate

public ThresholdEvaluatorState.Status evaluate(double dsValue,
                                               Long sequenceNumber)

Specified by:

evaluate in interface ThresholdEvaluatorState

evaluate

public ThresholdEvaluatorState.ValueStatus evaluate(ExpressionThresholdValue valueSupplier,
                                                    Long sequenceNumber)
                                             throws ThresholdExpressionException

Specified by:

evaluate in interface ThresholdEvaluatorState

Returns:

the value that was evaluated along with the resulting status

Throws:

ThresholdExpressionException

clearState

public void clearState()

Description copied from interface: ThresholdEvaluatorState

clearState

Specified by:

clearState in interface ThresholdEvaluatorState

reinitialize

public void reinitialize()

Specified by:

reinitialize in interface ReinitializableState

clearStateBeforePersist

protected abstract void clearStateBeforePersist()

evaluateAfterFetch

protected abstract ThresholdEvaluatorState.Status evaluateAfterFetch(double dsValue)

createBasicEvent

protected Event createBasicEvent(String uei,
                                 Date date,
                                 double dsValue,
                                 CollectionResourceWrapper resource,
                                 Map<String,String> additionalParams)

createBasicEvent

Parameters:

uei - a String object.

date - a Date object.

dsValue - a double.

resource - a CollectionResourceWrapper object.

additionalParams - a Map object.

Returns:

a Event object.

formatValue

protected String formatValue(double value)

formatValue

Parameters:

value - a Double object.

Returns:

a String object.

getThresholdingSession

public ThresholdingSession getThresholdingSession()

Specified by:

getThresholdingSession in interface ThresholdEvaluatorState

setInstance

public void setInstance(String instance)

Specified by:

setInstance in interface ThresholdEvaluatorState
