Метод	Описание
DatasetTemplate ( string dataTableName ) : DataSet	Returns a template DataSet that can be used for storing time-series data in a tabular format. The returned DataSet consists of two DataTables with the following structure: Table 1 is to be used for storing time-series data. Column Name Column Description Instance Historian instance providing the time-series data. ID IDataPoint.HistorianID of the time-series data. Time IDataPoint.Time of the time-series data. Value IDataPoint.Value of the time-series data. Quality IDataPoint.Quality of the time-series data. Table 2 is to be used for providing information about Table 1. Column Name Column Description RunTime DateTime (in UTC) when the data in Table 1 was populated. RecordCount Number of time-series data points in Table 1. RefreshSchedule Interval (in seconds) at which the data in Table 1 is to be refreshed.
Dispose ( ) : void	Releases all the resources used by the exporter.
Equals ( object obj ) : bool	Determines whether the current exporter object is equal to obj.
FindExport ( string exportName ) : Export	Returns the Export for the specified exportName from the Exports.
FindListener ( string listenerName ) : DataListener	Returns the DataListener for the specified listenerName from the Listeners.
GetHashCode ( ) : int	Returns the hash code for the current exporter object.
ProcessExport ( string exportName ) : void	Processes Export with the specified exportName.

Описание методов

DatasetTemplate() публичный статический Метод

Returns a template DataSet that can be used for storing time-series data in a tabular format.

The returned DataSet consists of two DataTables with the following structure:

Table 1 is to be used for storing time-series data. Column Name Column Description Instance Historian instance providing the time-series data. ID IDataPoint.HistorianID of the time-series data. Time IDataPoint.Time of the time-series data. Value IDataPoint.Value of the time-series data. Quality IDataPoint.Quality of the time-series data. Table 2 is to be used for providing information about Table 1. Column Name Column Description RunTime DateTime (in UTC) when the data in Table 1 was populated. RecordCount Number of time-series data points in Table 1. RefreshSchedule Interval (in seconds) at which the data in Table 1 is to be refreshed.
