Constructor Detail

AvailabilityDurationCacheElement

public AvailabilityDurationCacheElement(org.rhq.core.domain.alert.AlertConditionOperator operator,
                                        String operatorOption,
                                        org.rhq.core.domain.measurement.AvailabilityType value,
                                        int conditionTriggerId)

Parameters:

operator -

operatorOption - the duration, in seconds (as String)

value -

conditionTriggerId - this is actually the alertConditionId, renamed here.

Method Detail

checkCacheElements

public static void checkCacheElements(List<AvailabilityDurationCacheElement> cacheElements,
                                      org.rhq.core.domain.resource.Resource resource,
                                      org.rhq.core.domain.measurement.AvailabilityType providedValue)

Here we check to see if an availability change for a resource should initiate an avail duration check. For each relevant avail duration condition for the resource schedule a job to check the avail state after the condition's duration.

Parameters:

cacheElements -

resource -

providedValue -

matches

public boolean matches(org.rhq.core.domain.measurement.AvailabilityType providedValue,
                       Object... extraParams)

Overrides:

matches in class AbstractEnumCacheElement<org.rhq.core.domain.measurement.AvailabilityType>

getOperatorSupportsType

public org.rhq.core.domain.alert.AlertConditionOperator.Type getOperatorSupportsType(org.rhq.core.domain.alert.AlertConditionOperator operator)

Description copied from class: AbstractCacheElement

For the most part, the operator itself denotes whether it makes comparisons against a sliding scale or not. However, this doesn't hold in every conceivable scenario. Thus, the defaultSupportsType will support 95% of the use cases, and the AbstractCacheElement's getOperatorSupportsType will have a chance to override this.

Overrides:

getOperatorSupportsType in class AbstractEnumCacheElement<org.rhq.core.domain.measurement.AvailabilityType>
