Description Miloslav Metelka 2011-04-14 13:01:11 UTC
I would like to rewrite o.n.editor.Annotations to be more efficient:
1) Get rid of marks and the markChain.
2) Compute annotations combinations lazily once a particular line is about to be displayed.
3) Hold annotations in a vector according to their underlying position.
3) Possibly have a special handling by the view hierarchy rather than just a highlighting layer.
Comment 1 Vladimir Voskresensky 2011-04-14 13:31:47 UTC
Mila, as another perf improvements we'd like to see method:
updateAnnotations(collectionForRemove, collectionToAdd)

then we can prevent expensive sequence in clients code like:
for (anno: collectionForRemove) {

for (anno: collectionToAdd) {
