DefaultGraphSpecificsStrategy (JGraphT : a free Java graph library)

java.lang.Object
- org.jgrapht.graph.DefaultGraphSpecificsStrategy<V,E>

Type Parameters:

V - the graph vertex type

E - the graph edge type

All Implemented Interfaces:

Serializable, GraphSpecificsStrategy<V,E>
```
public class DefaultGraphSpecificsStrategy<V,E>
extends Object
implements GraphSpecificsStrategy<V,E>
```
A default lookup specifics strategy implementation.
Graphs constructed using this strategy require the least amount of memory, at the expense of slow edge retrievals. Methods which depend on edge retrievals, e.g. getEdge(V u, V v), containsEdge(V u, V v), addEdge(V u, V v), etc may be relatively slow when the average degree of a vertex is high (dense graphs). For a fast implementation, use FastLookupGraphSpecificsStrategy.

  - getIntrusiveEdgesSpecificsFactory
```
public 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.
    
    Specified by:
    
    getIntrusiveEdgesSpecificsFactory in interface GraphSpecificsStrategy<V,E>
    
    Returns:
    
    a function which creates intrusive edges specifics.
