[topicmapmail] Merging associations

[Joril Andersen]

Hi (soon weekend : ))

As I see it, the 2 topic maps have already been merged so the all the topics 
in A would have been added or merged to topic map B. In my implementation, 
the mergIn(TopicMap topicmap) first calls the mergeIn(Topic topic) and then 
the copyAssociations(TopicMap otherTM, HashTable mergeMap) method. The 
method then checks in the mergeMap for roles, players and types. If not 
contained in the mergeMap something has gone terribly wrong in the merging 
methods : /. So in other words, this should already have been taken care of 
: ) The topic.getRolesPlayed() is used in the mergeIn(Topic topic) method to 
set/replace the correct roles/types/players in all of the associations. So 
all of the associations should have the correct reference to the newly 
merged topics :)

Do you agree?
