public class VertexLongList extends Object implements VertexListInternal
VertexListInternal that stores only the vertex ids
and simply wraps an LongArrayList and keeps a boolean flag to remember whether this list is in sort order.
In addition, we need a transaction reference in order to construct actual vertex references on request.
This is a more efficient way to represent a vertex result set but only applies to loaded vertices that have ids.
So, compared to VertexArrayList this is an optimization for the special use case that a vertex is loaded.| Constructor and Description |
