ComputeChecksum() public method

This method computes a Checksum for the timeseries. The input to the hash includes the list of parameters of the time series, and the list of checksums for each of the traces in the time series ensemble. The list of the traces' checksums are passed to this method within a list of ITimeSeriesTrace objects. This method does not modify the object given in the traceList parameter or assign any property values to any of its items.
public ComputeChecksum ( TSDateCalculator timeStepUnit, short timeStepQuantity, System.DateTime blobStartDate, List traceList ) : byte[]
timeStepUnit TSDateCalculator TSDateCalculator.TimeStepUnitCode value for Minute,Hour,Day,Week,Month, Year, or Irregular
timeStepQuantity short The number of the given unit that defines the time step. /// For instance, if the time step is 6 hours long, then this value is 6.
blobStartDate System.DateTime Date of the first time step in the BLOB
traceList List a list of trace object whose checksums have already been computed.
