Constructor Detail

AbstractCacheElement

public AbstractCacheElement(AlertConditionOperator operator,
                            T value,
                            int conditionTriggerId)

process

matches

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

getOperatorSupportsType

public abstract AlertConditionOperator.Type getOperatorSupportsType(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.
