All Implemented Interfaces:
com.fasterxml.jackson.core.Versioned, Closeable, AutoCloseable
public class CsvParser extends com.fasterxml.jackson.core.base.ParserMinimalBase
JsonParser implementation used to expose CSV documents in form that allows other Jackson functionality to deal with it.

Implementation is based on a state-machine that pulls information using CsvDecoder.
