Since I made the ticket I've done some additional work available in a new sandbox (just for my own sake to keep track what I'm doing against 2.8 release)
The new stuff is topologyenforcement when adding or removing vertices, which means that other features intersecting vertices will be removed and an edge crossing a new vertex will be split so that another vertex intersects the new one. OpenLayers stuff added are vertexadded and vertexremoved events to the Vector layer and an improvement (?) to containsPoint to give info about which edge is crossing (if it is crossing). Example is at: http://dev.openlayers.org/sandbox/bjornharrtell/eventbasedtopology2/examples/topology.html I'd also like to say that while I'm more or less where I wanted to get functionally and have no current plans for further developent, new patches for #2125 aren't my highest priority, partially because I think the ticket/patch is good enough to discuss the matter of if/how/when to continue the work somehow. /Björn 2009/6/11 Björn Harrtell <bjorn.harrt...@gmail.com>: > I won't argue for the current name, and can see your point so.. we'll > see what happens :) > > Anyway, I put togheter the current code into a patch against current > trunk for further discussion which might help you review the source > (which would be highly appriciated): > > http://trac.openlayers.org/ticket/2125 > > /Björn > > On Thu, Jun 11, 2009 at 09:08, Eric Lemoine<eric.lemo...@camptocamp.com> > wrote: >> 2009/6/9 Björn Harrtell <bjorn.harrt...@gmail.com>: >>> Thanks Eric :) >>> >>> Details are important, though I would argue that >>> OpenLayers.TopologyRule is only one char shorter than >>> OpenLayers.Topology.Rule ;) >> >> I'm not trying to save chars here, but to avoid unnecessary deep >> namespaces.
