Examples of plugins.Freetalk.Message

plugins.Freetalk.Message
A Freetalk message. This class is supposed to be used by the UI directly for reading messages. The UI can obtain message objects by querying them from a MessageManager. A message has the usual attributes (author, boards to which it is posted, etc.) one would assume. There are two unique ways to reference a message: It's URI and it's message ID. The URI is to be given to the user if he wants to tell other people about the message, the message ID is to be used for querying the database for a message in a fast way. Activation policy: Class Message does automatic activation on its own. This means that objects of class Message can be activated to a depth of only 1 when querying them from the database. All methods automatically activate the object to any needed higher depth. @author xor (xor@freenetproject.org) @author saces
