static

Used by the Aggregators factory to create a new instance of the aggregate calculator.

Parameters

aggregateId	The aggregate function to apply.
startTime	The start time.
endTime	The end time.
processingInterval	The processing interval.
stepped	Whether to use stepped interpolation.
configuration	The aggregate configuration.

bool AggregateCalculatorStartEnd::UsesInterpolatedBounds ( )

virtual

Indicates whether this aggregate uses Interpolated Bounding Values.

Returns: True if this aggregate uses Interpolated bounding values and false if it uses Simple Bounding Values.
