public class LineChunkSource

extends ChunkSourceBase

Simplest possible Source: Reads a file and generates a chunk for every single line read. The only "major" feature: gzipped files are automagically unpacked while reading. This has proved to be quite useful for weblos, since those can be large and compress well..
