Constructor Detail

CASKS017DataHandler

public CASKS017DataHandler()
                    throws java.io.IOException

Creates a new instance of CASKS017DataHandler for handling CASKS017DataRecords stored in a formatted File The default File is hard coded. To specify the File use CASKS017DataHandler(File). To set a different default File edit the source code and recompile.

Throws:

java.io.IOException

CASKS017DataHandler

public CASKS017DataHandler(java.io.File formattedFile)

Creates a new instance of CASKS017DataHandler with Records loaded from formattedFile.

Parameters:

formattedFile - Formatted file of CASKS017DataRecords

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 CASKS017DataRecords and written to this.tRandomAccessFile.

Parameters:

sourceFile - The source CASKS017DataRecords file to be formatted and written to this.tRandomAccessFile.

RecordID - The RecordID to assign to the first CASKS017DataRecord.

Returns:

The RecordID assigned to the last CASKS017DataRecords.

Throws:

java.io.IOException

getDataRecord

public AbstractCASDataRecord getDataRecord(long RecordID)

Specified by:

getDataRecord in class AbstractCASDataHandler

Parameters:

RecordID - The RecordID of the CASKS017DataRecord to be returned.

Returns:

a CASKS017DataRecord with AbstractCASDataRecord.RecordID = RecordID

getCASKS017DataRecord

public CASKS017DataRecord getCASKS017DataRecord(long RecordID)

Parameters:

RecordID - The RecordID of the CASKS017DataRecord to be returned.

Returns:

a CASKS017DataRecord with CASKS017DataRecord.RecordID = RecordID

aggregateOAToWard

public void aggregateOAToWard(java.io.RandomAccessFile aRandomAccessFile,
