Method Summary

protected org.apache.tika.parser.Parser	getParser() The parser to be used to parse this kind of documents; subclasses should return always the same instance, as Tika parsers are immutable and thread-safe.
protected List<? extends TikaField>	metadataFields() The list of Tika fields (apart for content) that this factory provides; it returns the empty list, so most subclasses may want to override this method.
