Class PickBestTextEncodingParser

java.lang.Object

org.apache.tika.parser.AbstractParser

org.apache.tika.parser.multiple.AbstractMultipleParser

org.apache.tika.example.PickBestTextEncodingParser

All Implemented Interfaces:

Serializable, org.apache.tika.parser.Parser

Deprecated.

Currently not suitable for real use, more a demo / prototype!

public class PickBestTextEncodingParser
extends org.apache.tika.parser.multiple.AbstractMultipleParser

Inspired by TIKA-1443 and https://wiki.apache.org/tika/CompositeParserDiscussion this tries several different text encodings, then does the real text parsing based on which is "best".

The logic for "best" needs a lot of work!

This is not recommended for actual production use... It is mostly to prove that the AbstractMultipleParser environment is sufficient to support this use-case

TODO Implement proper "Junk" detection
