java.lang.Objectorg.ow2.weblab.core.extended.factory.SegmentFactory
public class SegmentFactory
To create Segment
s we strongly encourage to use this class. It will enable the creation of a
Segment
having an URI
compliant with the WebLabRI
recommendations.
Since an Segment
hasn't any sense without being attached to a MediaUnit
, we only provide a
method for creating Segment
s that takes a MediaUnit
in parameter. As a result, the created
Segment
(an instance of the Segment
class in
parameter) is added to the Segment
List
of the MediaUnit
.
