# Interface EdgeSetFactory<V,​E>

Type Parameters:
V - the graph vertex type
E - the graph edge type
All Known Implementing Classes:
ArrayUnenforcedSetEdgeSetFactory

public interface EdgeSetFactory<V,​E>
A factory for edge sets. This interface allows the creator of a graph to choose the Set implementation used internally by the graph to maintain sets of edges. This provides control over performance tradeoffs between memory and CPU usage.

• ### createEdgeSet

java.util.Set<E> createEdgeSet​(V vertex)
Create a new edge set for a particular vertex.
Parameters:
vertex - the vertex for which the edge set is being created; sophisticated factories may be able to use this information to choose an optimal set representation (e.g. ArrayUnenforcedSet for a vertex expected to have low degree, and LinkedHashSet for a vertex expected to have high degree)
Returns:
new set
