CHAPTER 21. INCREMENTAL REDISPLAY

=> propagate-output-record-changes record child mode &optional old-position old-bounding-
rectangle erases moves draws erase-overlapping move-overlapping check-overlapping [Generic Function]
Called when the changed child output record requires that its parent, record, be redisplayed as
well. propagate-output-record-changes will update the difference set to reflect the additional
changes.

check-overlapping is as for compute-difference-set.

=> match-output-records record &rest initargs [Generic Function]
Returns true if record matches the supplied class initargs initargs, otherwise returns false.

=> find-child-output-record record use-old-elements record-type &rest initargs &key unique-id
unique-id-test [Generic Function]
Finds a child of record matching the record-type and the supplied initargs initargs. unique-id and
unique-id-test are used to match against the children as well. use-old-elements controls whether
the desired record is to be found in the previous (before redisplay) contents of the record.

=> output-record-contents-ok record [Generic Function]
Returns true if the current state of record are up to date, otherwise returns false.

=> recompute-contents-ok record [Generic Function]
Compares the old (before redisplay) and new contents of record to determine whether or not this
record changed in such a way so that the display needs updating.

=> cache-output-record record child unique-id [Generic Function]
record stores child such that it can be located later using unique-id.

=> decache-child-output-record record child use-old-elements [Generic Function]
Invalidates the redisplay state of record.

=> find-cached-output-record record use-old-elements record-type &rest initargs &key unique-
id unique-id-test &allow-other-keys [Generic Function]
Finds a previously cached child matching record-type, initargs, unique-id, and unique-id-test. use-
old-elements controls whether the desired record is to be found in the previous (before redisplay)
contents of the record.
