Constructor Detail

CASKS09bDataHandler

public CASKS09bDataHandler()
                    throws java.io.IOException
Creates a new instance of CASKS09bDataHandler for handling CASKS09bDataRecords stored in a formatted File The default File is hard coded. To specify the File use CASKS09bDataHandler(File). To set a different default File edit the source code and recompile.

Throws:
java.io.IOException

CASKS09bDataHandler

public CASKS09bDataHandler(java.io.File formattedFile)
Creates a new instance of CASKS09bDataHandler with Records loaded from formattedFile.

Parameters:
formattedFile - Formatted file of CASKS09bDataRecords
Method Detail

main

public static void main(java.lang.String[] args)
                 throws java.io.IOException
Parameters:
args - the command line arguments No arguments are used.
Throws:
java.io.IOException

formatSourceData

protected void formatSourceData(java.io.File directory,
                                int n)
                         throws java.io.IOException
Loads CAS001DataRecords and prints out n randomly

Parameters:
directory - to load source data from
n - the number of loaded data records to print out.
Throws:
java.io.IOException

format

protected long format(java.io.File sourceFile,
                      long RecordID)
               throws java.io.IOException
Uses a BufferedReader and a StreamTokenizer to read lines from the sourceFile File. The lines are converted to CASKS09bDataRecords and written to this.tRandomAccessFile.

Parameters:
sourceFile - The source CASKS09bDataRecords file to be formatted and written to this.tRandomAccessFile.
RecordID - The RecordID to assign to the first CASKS09bDataRecord.
Returns:
The RecordID assigned to the last CASKS09bDataRecords.
Throws:
java.io.IOException

getDataRecord

public AbstractCASDataRecord getDataRecord(long RecordID)
Specified by:
getDataRecord in class AbstractCASDataHandler
Parameters:
RecordID - The RecordID of the CASKS09bDataRecord to be returned.
Returns:
a CASKS09bDataRecord with AbstractCASDataRecord.RecordID = RecordID

getCASKS09bDataRecord

public CASKS09bDataRecord getCASKS09bDataRecord(long RecordID)
Parameters:
RecordID - The RecordID of the CASKS09bDataRecord to be returned.
Returns:
a CASKS09bDataRecord with CASKS09bDataRecord.RecordID = RecordID

aggregateOAToWard

public void aggregateOAToWard(java.io.RandomAccessFile aRandomAccessFile,
                              long startRecordID,
