- Type Parameters:
V
- the graph vertex typeE
- the graph edge type
- All Implemented Interfaces:
java.io.Serializable
,GraphSpecificsStrategy<V,E>
public class FastutilFastLookupGSS<V,E> extends java.lang.Object implements GraphSpecificsStrategy<V,E>
The fast lookup specifics strategy implementation using fastutil maps for storage..Graphs constructed using this strategy use additional data structures to improve the performance of methods which depend on edge retrievals, e.g. getEdge(V u, V v), containsEdge(V u, V v),addEdge(V u, V v). A disadvantage is an increase in memory consumption. If memory utilization is an issue, use the
FastutilGSS
instead.- See Also:

getSpecificsFactory
public java.util.function.BiFunction<Graph<V,E>,GraphType,Specifics<V,E>> getSpecificsFactory()
Description copied from interface:GraphSpecificsStrategy
Get a function which creates the specifics. The factory will accept the graph type as a parameter.- Specified by:
getSpecificsFactory
in interfaceGraphSpecificsStrategy<V,E>
- Returns:
- a function which creates intrusive edges specifics.
-
getIntrusiveEdgesSpecificsFactory
public java.util.function.Function<GraphType,IntrusiveEdgesSpecifics<V,E>> getIntrusiveEdgesSpecificsFactory()
Description copied from interface:GraphSpecificsStrategy
Get a function which creates the intrusive edges specifics. The factory will accept the graph type as a parameter.Note that it is very important to use a map implementation which respects iteration order.
