Class FileTypeHelper

java.lang.Object
org.codelibs.fess.helper.FileTypeHelper
public class FileTypeHelper extends Object
Helper class for managing file type mappings based on MIME types. This class provides functionality to map MIME types to file types and retrieve appropriate file type classifications for documents during indexing. The mappings are loaded from configuration and can be dynamically modified at runtime. When a MIME type is not found in the mapping, a default value is returned.
