A Mime Decoder is a class that implements the
MimeDecoder interface. It can be used by a
MessageComposer implementation to decode a binary array, transforming it into a specific type of Java Object. (The type of object is determined by the “mime type” of the binary-encoded data.)
Examples of gateways that use the MimeDecoder mechanism are the File and FTP Gateway Listeners. These gateways can be configured with ”mimeType” or “mimeDecoder” properties, which triggers automatic installation of the appropriate MimeDecoder implementation for the specified mime type.
