메소드	설명
CloseConnection ( int connectionNumber ) : void	Closes the connection identified with the given serial number. When the connection is closed, it is removed from the list of connections available to the time series library, and the serial number no longer refers to this connection.
ComputeChecksum ( TSDateCalculator timeStepUnit, short timeStepQuantity, System.DateTime blobStartDate, List traceList ) : byte[]	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.
ConvertBlobToListAll ( TSDateCalculator timeStepUnit, short timeStepQuantity, int timeStepCount, System.DateTime blobStartDate, Byte blobData, List &dateValueList, int compressionCode ) : int	This method creates a List of TimeSeriesValue objects from the given BLOB (byte array) of time series values. The method converts the entire BLOB into the list. The sibling method ConvertBlobToListLimited can convert a selected portion of the BLOB into the list.
ConvertBlobToListLimited ( TSDateCalculator timeStepUnit, short timeStepQuantity, int timeStepCount, System.DateTime blobStartDate, int nReqValues, System.DateTime reqStartDate, System.DateTime reqEndDate, Byte blobData, List &dateValueList, int compressionCode ) : int	This method creates a List of TimeSeriesValue objects from the given BLOB (byte array) of time series values. The method takes parameters for a maximum number of values, an earliest date, and a latest date, so that only a portion of the BLOB might be converted to the List. The sibling method ConvertBlobToListAll can convert the entire BLOB without any limits.
ConvertListToBlobWithChecksum ( TSDateCalculator timeStepUnit, short timeStepQuantity, int timeStepCount, System.DateTime blobStartDate, System.DateTime blobEndDate, List dateValueList, ITimeSeriesTrace traceObject, int &compressionCode ) : byte[]	This method converts a List of TimeSeriesValue objects into a BLOB (byte array) of time series values and computes a checksum from the BLOB. This method assigns the new values of the ValueBlob, Checksum, EndDate, and TimeStepCount to the object given in the traceObject parameter. The TraceNumber property of the traceObject parameter must be set before calling this method. The entire List is converted into the BLOB--i.e., the method does not take any parameters for limiting the size of the List that is created. This method will throw exceptions if the meta-parameters that are passed in are not consistent with the List of TimeSeriesValue objects.
CountTimeSteps ( System.DateTime startDate, System.DateTime endDate, short unit, short stepSize ) : int
DeleteMatchingSeries ( int connectionNumber, String tableName, String traceTableName, String whereClause ) : bool	This method deletes any records from the table which match the given WHERE clause of a SQL command, using the given database connection number and database table name.
DeleteSeries ( int connectionNumber, String tableName, String traceTableName, int id ) : bool	This method deletes a record for a single time series from the database, using the given database connection number and database table name.
FillDateArray ( TSDateCalculator timeStepUnit, short timeStepQuantity, int nReqValues, System.DateTime dateArray, System.DateTime reqStartDate ) : void
FillSeriesDateArray ( int connectionNumber, String tableName, String traceTableName, int id, int nReqValues, System.DateTime dateArray, System.DateTime reqStartDate ) : void
GetConnectionFromId ( int connectionNumber ) : SqlConnection	Returns the SqlConnection object corresponding to the given connection number.
IncrementDate ( System.DateTime startDate, TSDateCalculator unit, short stepSize, int numSteps ) : System.DateTime
OpenConnection ( String connectionString ) : int	Opens a new connection for the time series library to use. The new connection is added to a list and assigned a serial number within the list. The method returns the serial number of the new connection.
XmlImport ( String xmlFileName, List tsImportList ) : int	This method reads the given XML file and stores each time series that is defined in the XML file to a new TSImport object that is added to the given List of TSImport objects.
XmlImportAndSaveToDB ( int connectionNumber, String tableName, String traceTableName, String xmlFileName, List tsImportList ) : int	This method reads the given XML file and stores any time series that are defined in the XML file to the database using the given database connection number and database table name. Each time series is also stored in a new TSImport object that is addded to the given List of TSImport objects.
XmlImportFromString ( String xmlString, List tsImportList ) : int	This method reads the given XML string and stores each time series that is defined in the XML file to a new TSImport object that is added to the given List of TSImport objects.
