Examples of plugins.Freetalk.MessageList

plugins.Freetalk.MessageList

A MessageList contains a list of MessageReference objects. Each MessageReference object contains the CHK URI of the referenced Message, the ID of the message and a single

Board> to which the Message belongs. If a Message belongs to multiple boards, a MessageReference is stored for each of them. Constraints: - A MessageList must map the ID of a contained message to a single URI. - A MessageList should not contain multiple mapppings of a URI to the same board. This is considered as DoS - A MessageList should maybe be limited to a maximal amount of messages references. - There should be a limit to a certain maximal amount of boards a message can be posted to. Activation policy: Class MessageList (and it's member classes) does automatic activation on its own. This means that objects of class MessageList 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.
