Class ClosestNewLineChunker

java.lang.Object

com.mware.ge.csv.CharReadableChunker

com.mware.ge.csv.ClosestNewLineChunker

All Implemented Interfaces:

Chunker, Closeable, AutoCloseable

public class ClosestNewLineChunker
extends CharReadableChunker

In a scenario where there's one reader reading chunks of data, handing those chunks to one or more processors (parsers) of that data, this class comes in handy. This pattern allows for multiple seeker instances, each operating over one chunk, not transitioning itself into the next.
