Constructor Detail

CAS044DataHandler

public CAS044DataHandler()
                  throws java.io.IOException

Creates a new instance of CAS044DataHandler for handling CAS044DataRecords stored in a formatted File The default File is hard coded. To specify the File use CAS044DataHandler(File). To set a different default File edit the source code and recompile.

Throws:

java.io.IOException

CAS044DataHandler

public CAS044DataHandler(java.io.File formattedFile)
                  throws java.io.IOException

Creates a new instance of CAS044DataHandler with Records loaded from formattedFile.

Parameters:

formattedFile - Formatted file of CAS044DataRecords

Throws:

java.io.IOException

Method Detail

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 CAS044DataRecords and written to this._RandomAccessFile.

Parameters:

sourceFile - The source CAS044DataRecords file to be formatted and written to this._RandomAccessFile.

RecordID - The RecordID to assign to the first CAS044DataRecord.

Returns:

The RecordID assigned to the last CAS044DataRecords.

Throws:

java.io.IOException

getDataRecord

public AbstractCASDataRecord getDataRecord(long RecordID)

Specified by:

getDataRecord in class AbstractCASDataHandler

Parameters:

RecordID - The RecordID of the CAS044DataRecord to be returned.

Returns:

a CAS044DataRecord with AbstractCASDataRecord.RecordID = RecordID

getCAS044DataRecord

public CAS044DataRecord getCAS044DataRecord(long RecordID)

Parameters:

RecordID - The RecordID of the CAS044DataRecord to be returned.

Returns:

a CAS044DataRecord with CAS044DataRecord.RecordID = RecordID

aggregateOAToWard

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