Method Detail

setFormat

public void setFormat(ReadOnlyProperty formatProps)
               throws FormatException

provide the reader with the property tree that defines the format of the files it must read.

Parameters:

formatProps - property tree defining output file format. See subclass implementations.

FormatException

write

public void write(RecordData record)
           throws IOException

read raw data records from an input stream, convert them to (@link RecordData} objects using the format properties, and notify the handler provided. Send any edit/reject reject records to the specified reject stream.

IOException

writeRecord

public void writeRecord(String formattedRecord)

writeDateRecord

public void writeDateRecord(Date date,
                            String format)

flush

public void flush()
           throws IOException

flush any buffered contents to the stream.

IOException

close

public void close()
           throws IOException

close down the writer and flush all the data to the underlying output stream. This does not close the output stream.

IOException

createRawData

protected abstract String[] createRawData(RecordData record)

create a record ready to go out to the ouput stream from an RecordData object. Format based on the properties provided to the setFormat(org.arch4j.propertytree.ReadOnlyProperty) method.

Parameters:

record - the record object to be converted to Strings.

Returns:

String representation of record.

writeRawData

protected void writeRawData(String[] rawBuffer)

write a set of strings representing a record out to the ouput stream.

Parameters:

rawBuffer - raw data to send to output file.

initFormatData

protected abstract void initFormatData()
                                throws FormatException

FormatException

convertObjectToText

protected String convertObjectToText(Object value,
                                     String aDateFormat)
