I'm utilizing ActiveMQ to push objects onto a map. As messages are
received a "database" on the client side is built to determine if this
is a new object, or just an update to an existing object. Currently,
I'm removing the existing marker and then adding a new marker for an
updated. This seems pretty in-efficient. Any ideas?
if(marker!=null){ //it's an update
markers.removeMarker(marker);
icon = new
OpenLayers.Icon(message.getElementsByTagName("icon")[0].getAttribute('sr
c'),size);
marker = new OpenLayers.Marker(new OpenLayers.LonLat(x,y),icon);
_objDatabase.put(id, marker);
markers.addMarker(marker);
}else{ //new item
icon = new
OpenLayers.Icon(message.getElementsByTagName("icon")[0].getAttribute('sr
c'),size);
marker = new OpenLayers.Marker(new OpenLayers.LonLat(x,y),icon);
markers.addMarker(marker);
_objDatabase.put(id, marker);
}
