AFData Methods

The AFData type exposes the following members.

Methods

	Name	Description
	CreateWithInputDataProvider	Creates a new AFData instance that will evaluate this attribute with input data obtained by the specified input data provider.
	EndOfStream	Returns the end-of-stream AFValue.
	EndOfStreamAsync	Get the value with the largest timestamp for a data stream.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	FilteredSummaries	This method, when supplied a filter expression that evaluates to true or false, evaluates it over the passed time range. For the time ranges where the expression evaluates to true, the method calculates the requested summaries on the source attribute.
	FilteredSummariesAsync	This method, when supplied a filter expression that evaluates to true or false, evaluates it over the passed time range. For the time ranges where the expression evaluates to true, the method calculates the requested summaries on the source attribute.
	GetAllCachedValues	Get all the events in the AFDataCache for this AFData instance.
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	InterpolatedValue	Returns a single AFValue whose value is interpolated at the passed time.
	InterpolatedValueAsync	Returns a single AFValue whose value is interpolated at the passed time.
	InterpolatedValues	Retrieves interpolated values over the specified time range at the specified sampling interval.
	InterpolatedValuesAsync	Retrieves interpolated values over the specified time range at the specified sampling interval.
	InterpolatedValuesAtTimes	Retrieves interpolated values at the specified times.
	InterpolatedValuesAtTimesAsync	Retrieves interpolated values at the specified times.
	PlotValues	Retrieves values over the specified time range suitable for plotting over the number of intervals (typically represents pixels).
	PlotValuesAsync	Retrieves values over the specified time range suitable for plotting over the number of intervals (typically represents pixels).
	RecordedValue	Returns a single recorded AFValue based on the passed time and mode.
	RecordedValueAsync	Returns a single recorded AFValue based on the passed time and mode.
	RecordedValues	Returns a list of compressed values for the requested time range from the source provider.
	RecordedValuesAsync	Returns a list of values for the requested time range from the source provider.
	RecordedValuesAtTimes	Retrieves recorded values at the specified times.
	RecordedValuesAtTimesAsync	Retrieves recorded values at the specified times.
	RecordedValuesByCount	This method returns a specified number of compressed values beginning at the requested start time in the direction specified.
	RecordedValuesByCountAsync	This method returns a specified number of compressed values beginning at the requested start time in the direction specified.
	ReplaceValues(AFTimeRange, AFValues)	This method removes existing data within the specified AFTimeRange and inserts the specified values on the target system using the configured data reference.
	ReplaceValues(AFTimeRange, AFValues, AFBufferOption)	This method removes existing data within the specified AFTimeRange and inserts the specified values on the target system using the configured data reference.
	ReplaceValuesAsync(AFTimeRange, AFValues, CancellationToken)	This method removes existing data within the specified AFTimeRange and inserts the specified values on the target system using the configured data reference.
	ReplaceValuesAsync(AFTimeRange, AFValues, AFBufferOption, CancellationToken)	This method removes existing data within the specified AFTimeRange and inserts the specified values on the target system using the configured data reference.
	Summaries	Returns several summaries for a single attribute over a time range for each interval within the range.
	SummariesAsync	Returns several summaries for a single attribute over a time range for each interval within the range.
	Summary	Returns several summaries for a single attribute over a single time range.
	SummaryAsync	Returns several summaries for a single attribute over a single time range.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	UpdateValue(AFValue, AFUpdateOption)	This method writes, replaces, or removes a value on the target system using the configured data reference.
	UpdateValue(AFValue, AFUpdateOption, AFBufferOption)	This method writes, replaces, or removes a value on the target system using the configured data reference.
	UpdateValues(AFValues, AFUpdateOption)	This method writes or replaces one or more values on the target system using the configured data reference.
	UpdateValues(AFValues, AFUpdateOption, AFBufferOption)	This method writes or replaces one or more values on the target system using the configured data reference.
	UpdateValuesAsync(AFValues, AFUpdateOption, CancellationToken)	This method writes or replaces one or more values on the target system using the configured data reference.
	UpdateValuesAsync(AFValues, AFUpdateOption, AFBufferOption, CancellationToken)	This method writes or replaces one or more values on the target system using the configured data reference.
