Constructor Detail

AbstractCacheElement

public AbstractCacheElement(org.rhq.core.domain.alert.AlertConditionOperator operator,
                    T value,
                    int conditionTriggerId)

AbstractCacheElement

public AbstractCacheElement(org.rhq.core.domain.alert.AlertConditionOperator operator,
                    Object operatorOption,
                    T value,
                    int conditionId)

Method Detail

setNextCacheElement

public void setNextCacheElement(AbstractCacheElement<?> nextCacheElement)

getAlertConditionOperator

public org.rhq.core.domain.alert.AlertConditionOperator getAlertConditionOperator()

getAlertConditionOperatorOption

public Object getAlertConditionOperatorOption()

getAlertConditionValue

public T getAlertConditionValue()

setAlertConditionValue

public void setAlertConditionValue(T updatedValue)

getAlertConditionTriggerId

public int getAlertConditionTriggerId()

getActivity

public CacheElementActivity getActivity()

setActivity

public void setActivity(CacheElementActivity activity)

process

public final boolean process(T providedValue,
              Object... extraParams)

matches

public abstract boolean matches(T providedValue,
              Object... extras)

getOperatorSupportsType

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

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.
