private void expand(Iterable<FcgVertex> sources, FcgLevel sourceLevel, FcgDirection direction) {

		// remove any non-expandable vertices
		sources = IterableUtils.filteredIterable(sources, v -> v.canExpand());
		if (IterableUtils.isEmpty(sources)) {
			return;
		}

		FcgLevel expandingLevel = sourceLevel.child(direction);

		Set<FcgEdge> newEdges = getModelEdges(sources, expandingLevel, edgeNotInGraphFilter);

		// Need all vertices from the source level, as well as their edges.  
		// This is used to correctly layout the vertices we are adding.  This way, if we 
		// later add the sibling vertices, they will be in the correct spot, without clipping.
		Iterable<FcgVertex> sourceSiblings = getVerticesByLevel(sourceLevel);
		Set<FcgEdge> parentLevelEdges = getModelEdges(sourceSiblings, expandingLevel, unfiltered);

		Set<FcgVertex> newVertices = toVertices(newEdges, direction, vertexInGraphFilter.negate());
		boolean isIncoming = direction == IN;
		FcgExpandingVertexCollection collection =
			new FcgExpandingVertexCollection(sources, sourceLevel, expandingLevel, newVertices,
				newEdges, parentLevelEdges, isIncoming, view.getPrimaryGraphViewer());

		doExpand(collection);

		markExpanded(sources, direction, true);
