Constructor Detail

CAS002DataHandler

public CAS002DataHandler()

Creates a new instance of CAS002DataHandler loading a default file.

CAS002DataHandler

public CAS002DataHandler(java.io.File aFile)

Creates a new instance of CAS002DataHandler with Records loaded from aFile.

Parameters:

aFile - Formatted file of CAS002DataRecords.

Method Detail

formatSourceData

protected void formatSourceData(java.io.File directory,
                                int n)
                         throws java.io.IOException

Loads CAS002DataRecords 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

aggregateOAToWardForLeeds

public void aggregateOAToWardForLeeds()
                               throws java.io.IOException

Aggregate From OA To Ward For Leeds

Throws:

java.io.IOException

format

protected long format(java.io.File sourceFile,

               throws java.io.IOException

Uses a BufferedReader and a StreamTokenizer to read lines from the sourceFile File. The lines are converted to CAS002DataRecords and written to this.tRandomAccessFile.

Parameters:

sourceFile - The source CAS002DataRecords file to be formatted and written to this.tRandomAccessFile.

RecordID - The RecordID to assign to the first CAS002DataRecord.

Returns:

The RecordID assigned to the last CAS002DataRecords.

Throws:

java.io.IOException

getDataRecord

public AbstractCASDataRecord getDataRecord(long RecordID)

Specified by:

getDataRecord in class AbstractCASDataHandler

Parameters:

RecordID - The RecordID of the CAS002DataRecord to be returned.

Returns:

a CAS002DataRecord with AbstractCASDataRecord.RecordID = RecordID

getCAS002DataRecord

public CAS002DataRecord getCAS002DataRecord(long RecordID)

Parameters:

RecordID - The RecordID of the CAS002DataRecord to be returned.

Returns:
