Constructor Detail

CASKS002DataHandler

public CASKS002DataHandler()

CASKS002DataHandler

public CASKS002DataHandler(java.io.File formattedFile)

Creates a new instance of CASKS002DataHandler with Records loaded from formattedFile.

Parameters:

formattedFile - Formatted file of CASKS002DataRecords

Method Detail

formatSourceData

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

Loads CAS001DataRecords and prints out n randomly

Parameters:

directory - to load source data from

n - the number of loaded data records to print out.

format

protected long format(java.io.File sourceFile,
                      long RecordID)

Uses a BufferedReader and a StreamTokenizer to read lines from the sourceFile File. The lines are converted to CASKS002DataRecords and written to this.tRandomAccessFile.

Parameters:

sourceFile - The source CASKS002DataRecords file to be formatted and written to this.tRandomAccessFile.

RecordID - The RecordID to assign to the first CASKS002DataRecord.

Returns:

The RecordID assigned to the last CASKS002DataRecords.

getDataRecord

public AbstractCASDataRecord getDataRecord(long RecordID)

Specified by:

getDataRecord in class AbstractCASDataHandler

Parameters:

RecordID - The RecordID of the CASKS002DataRecord to be returned.

Returns:

a CASKS002DataRecord with AbstractCASDataRecord.RecordID = RecordID

getCASKS002DataRecord

public CASKS002DataRecord getCASKS002DataRecord(long RecordID)

Parameters:

RecordID - The RecordID of the CASKS002DataRecord to be returned.

Returns:

a CASKS002DataRecord with CASKS002DataRecord.RecordID = RecordID

aggregateOAToWard

public void aggregateOAToWard(java.io.RandomAccessFile aRandomAccessFile,
                              long startRecordID,
                              long endRecordID)
                       throws java.io.IOException

Aggregates CASKS002DataRecords from OA To Ward for the OA records in the range [startRecordID,endRecordID] and writes the results to aRandomAccessFile

Parameters:

aRandomAccessFile - RandomAccessFile to which results are written

startRecordID - The first OA RecordID in the sequence to be aggregated.

endRecordID - The last OA RecordID in the sequence to be aggregated.

Throws:

java.io.IOException

aggregateOAToMSOA

public void aggregateOAToMSOA(java.io.RandomAccessFile aRandomAccessFile,
                              long startRecordID,
                              long endRecordID)

Aggregates CASKS002DataRecords from OA To MSOA for the OA records in the range [startRecordID,endRecordID] and writes the results to aRandomAccessFile

Parameters:

aRandomAccessFile - RandomAccessFile to which results are written

startRecordID - The first OA RecordID in the sequence to be aggregated.

endRecordID - The last OA RecordID in the sequence to be aggregated.
