All Implemented Interfaces:

FessTransformer, org.codelibs.fess.crawler.transformer.Transformer

public class FessFileTransformer
extends AbstractFessFileTransformer

File transformer implementation for the Fess search engine. This transformer handles file-based document transformation and content extraction using the Fess file transformation process with support for various file types.

It extends AbstractFessFileTransformer to provide specialized file processing capabilities using the appropriate extractor for each file type.
