Interface IntrusiveEdgesSpecifics<V,E>

Type Parameters:
V - the graph vertex type
E - the graph edge type
All Superinterfaces:
Serializable
All Known Implementing Classes:
UniformIntrusiveEdgesSpecifics, WeightedIntrusiveEdgesSpecifics
public interface IntrusiveEdgesSpecifics<V,E> extends Serializable
An interface for the set of intrusive edges of a graph.

Since the library supports edges which can be any user defined object, we need to provide explicit support for storing vertex source, target and weight.
