Description copied from interface: BaseProcessor

This method will be called just before looping over the sequence of CDX lines. Intermediary processor must call begin() on nested processor.

writeHeader

protected void writeHeader(org.archive.format.cdx.CDXLine firstLine)

writeHeaderAndFirstLine

protected void writeHeaderAndFirstLine(org.archive.format.cdx.CDXLine line,
                                       String first,
                                       String last)

writeLine

public int writeLine(org.archive.format.cdx.CDXLine line)

Description copied from interface: BaseProcessor

Process line.

Parameters:

line - CDXLine

Returns:

1 if line is sent to output, 0 otherwise.

writeResumeKey

public void writeResumeKey(String resumeKey)

Description copied from interface: BaseProcessor

Write resumption key. Only the final CDXWriter should do actual work. All intermediaries shall simply call writeResumeKey(resumeKey) on nested processor.

end

public void end()

Description copied from interface: BaseProcessor

Called at the end. Perform any clean ups / finalizations here. Intermediaries processor should call end() on nested processor.
