Class MediaRedirect

com.exedio.cope.Feature

com.exedio.cope.Pattern

com.exedio.cope.pattern.MediaPath

com.exedio.cope.pattern.MediaRedirect

All Implemented Interfaces:

Serializable

public final class MediaRedirect
extends MediaPath

Specifies a http redirect (moved permanently) to a Media.

Common usage is to maintain old urls after renaming a Media. For instance, if there is a media picture:

 static final Media picture = new Media(OPTIONAL);
 

and this media is renamed to image:

 static final Media image = new Media(OPTIONAL);
 

then old urls created by picture can be supported with an additional:

 static final MediaRedirect picture = new MediaRedirect(image);
