Interface NewsMessage

All Superinterfaces:

Message

public interface NewsMessage
extends Message

An instance of NewsMessage defines the headline text that provides a brief description of a news story (see StoryMessage).

An object implementing this interface cannot be instantiated directly, but can be constructed using the MessageFactory.createNewsMessage(String, String, String, String) method of the MessageFactory that is available on the Publisher interface.

If this NewsMessage has a corresponding story for the headline, call the setStoryReference(String) method to uniquely identify that story. To record any keywords that can be used to locate the story in a search result call getTags(). This method returns a reference to a list of the keywords (if any) in the NewsMessage. You can then add additional keywords to the list.
