Class WarcWriterFactory

java.lang.Object
  org.jwat.warc.WarcWriterFactory

public class WarcWriterFactory
extends Object

Factory used for creating WarcWriter instances. Factory methods are available for creating WarcWriter instances for writing either compressed or uncompressed records. Use of buffered methods and/or buffering speeds up the writer considerably.
