java.lang.Object
  dekoh.portal.fwk.persistence.search.TagCloud

All Implemented Interfaces:

Iterable

public class TagCloud
extends Object
implements Iterable

TagCloud is a collection of tags ordered on popularity(number of DigitalObjects tagged). A tag cloud can be trimmed to specifying size.

Once tag Cloud is created Ordered sequence of tags can be obtained using TagCloud.getTagCloudEntries() method. Each TagCloudEntry will contain the popularity and its rank in the cloud.
