public class ReferredAttachments
extends Attachments

An attachment builder where, aside from storing the binary data in the database, you can point out a binary resource on another server using an url. Basic support for sucha field is in AbstractServletBuidler. This builder defines a default url field ('url'), has a better GUI function, and determines file size, filename, and mimetype from a referred to file when the url changes.

Since:

MMBase-1.8
