N - Node parameter typeE - Edge parameter typefinal class StandardMutableNetwork<N,E> extends StandardNetwork<N,E> implements MutableNetwork<N,E>
MutableNetwork that supports both directed and undirected
graphs. Instances of this class should be constructed with NetworkBuilder.
Time complexities for mutation methods are all O(1) except for removeNode(N node),
which is in O(d_node) where d_node is the degree of node.

builder.public boolean addNode(N node)
MutableNetworknode if it is not already present.
Nodes must be unique, just as Map keys must be. They must also be non-null.
addNode in interface MutableNetwork<N,E>true if the network was modified as a result of this callprivate NetworkConnections<N,E> addNodeInternal(N node)
node to the graph and returns the associated NetworkConnections.java.lang.IllegalStateException - if node is already presentpublic boolean addEdge(N nodeU, N nodeV, E edge)
MutableNetworkedge connecting nodeU to nodeV.
If the graph is directed, edge will be directed in this graph; otherwise, it will be
undirected.
edge must be unique to this graph, just as a Map key must be. It must
also be non-null.
If nodeU and nodeV are not already present in this graph, this method will
silently add nodeU and nodeV to the graph.
If edge already connects nodeU to nodeV (in the specified order if
this network Network.isDirected(), else in any order), then this method will have no effect.
addEdge in interface MutableNetwork<N,E>true if the network was modified as a result of this callpublic boolean addEdge(EndpointPair<N> endpoints, E edge)
MutableNetworkedge connecting endpoints. In an undirected network, edge will
also connect nodeV to nodeU.
If this graph is directed, edge will be directed in this graph; if it is undirected,
edge will be undirected in this graph.
If this graph is directed, endpoints must be ordered.
edge must be unique to this graph, just as a Map key must be. It must
also be non-null.
If either or both endpoints are not already present in this graph, this method will silently
add each missing endpoint to the graph.
If edge already connects an endpoint pair equal to endpoints, then this
method will have no effect.
