TOPICA Basic Class RecordRelation

[This is preliminary documentation and is subject to change.]

The RecordRelation class models one relation between two records (objects of the Record class).

Caution
This class only exists in TOPICA relases 4.24 and newer!

Currently (release 4.24), RecordRelation objects are created (by the TOPICA framework) to log "copy" and "move" operations. However, RecordRelation objects may be use for any type of relation between records (implemented in lateer releases of the framwwork and/or for configuration specific purposes).

A RecordRelation is directed, i.e. there is a "from" record and a "to" record.

As each Record object has a relation to a Patient object, there is also the concept of "from" and "to" patient. These may be the same (as the result of a normal "copy" operation), or they may be different (a "merge" operation, merging data from one patient to an other, is implemented as a number of "copy" operations from the source patient to the destination patient).
