Constructor Detail

UniqueDuplicateCount

public UniqueDuplicateCount(UniqCommand command,
                            ExecutionContext context,
                            LineProcessor output)

Method Detail

processLine

protected boolean processLine(Line line,
                              LineProcessor output)

Specified by:

processLine in class UniqProcessor

finish

public void finish()

Description copied from interface: LineProcessor

Indicates that this line processing task is complete and can finished.

Simple output devices usually perform a flush operation in this method. More complex commands may perform the real operation in this method, for instance write the total count of lines or words to the target file or stream.

writeLine

protected abstract void writeLine(Line line,
                                  long count,
                                  LineProcessor output)
