- Type Parameters:
V- the graph vertex type
E- the graph edge type
- All Implemented Interfaces:
public class ParanoidGraph<V,E> extends GraphDelegator<V,E>
ParanoidGraph provides a way to verify that objects added to a graph obey the standard equals/hashCode contract. It can be used to wrap an underlying graph to be verified. Note that the verification is very expensive, so ParanoidGraph should only be used during debugging.

g- the underlying wrapped graph
Adds the specified edge to this graph, going from the source vertex to the target vertex. More formally, adds the specified edge,
e, to this graph if this graph contains no edge
e2.equals(e). If this graph already contains such an edge, the call leaves this graph unchanged and returns
false. Some graphs do not allow edge-multiplicity. In such cases, if the graph already contains an edge from the specified source to the specified target, then this method does not change the graph and returns
false. If the edge was added to the graph, returns
The source and target vertices must already be contained in this graph. If they are not found in graph IllegalArgumentException is thrown.
- Specified by:
sourceVertex- source vertex of the edge.
targetVertex- target vertex of the edge.
e- edge to be added to this graph.
trueif this graph did not already contain the specified edge.

public boolean addVertex(V v)Adds the specified vertex to this graph if not already present. More formally, adds the specified vertex,
v, to this graph if this graph contains no vertex
u.equals(v). If this graph already contains such vertex, the call leaves this graph unchanged and returns
false. In combination with the restriction on constructors, this ensures that graphs never contain duplicate vertices.
