@Beta public interface MutableNetwork<N,E> extends Network<N,E>
A subinterface ofNetwork
which adds mutation methods. When mutation is not required, users should prefer theNetwork
interface. Since:

Method Detail

addNode
@CanIgnoreReturnValue boolean addNode(N node)
Addsnode
if it is not already present.Nodes must be unique, just as
Map
keys must be. They must also be nonnull. Returns:
true
if the network was modified as a result of this call

addEdge
@CanIgnoreReturnValue boolean addEdge(N nodeU, N nodeV, E edge)
Addsedge
connectingnodeU
tonodeV
.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 aMap
key must be. It must also be nonnull.If
nodeU
andnodeV
are not already present in this graph, this method will silentlyadd
nodeU
andnodeV
to the graph.If
edge
already connectsnodeU
tonodeV
(in the specified order if this networkNetwork.isDirected()
, else in any order), then this method will have no effect. Returns:
true
if the network was modified as a result of this call Throws:
IllegalArgumentException
 ifedge
already exists in the graph and does not connectnodeU
tonodeV
IllegalArgumentException
 if the introduction of the edge would violateNetwork.allowsParallelEdges()
orNetwork.allowsSelfLoops()

addEdge
@CanIgnoreReturnValue boolean addEdge(EndpointPair<N> endpoints, E edge)
Addsedge
connectingendpoints
. In an undirected network,edge
will also connectnodeV
tonodeU
.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 aMap
key must be. It must also be nonnull.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 toendpoints
, then this method will have no effect. Returns:
true
if the network was modified as a result of this call Throws:
IllegalArgumentException
 ifedge
already exists in the graph and connects some other endpoint pair that is not equal toendpoints
IllegalArgumentException
 if the introduction of the edge would violateNetwork.allowsParallelEdges()
orNetwork.allowsSelfLoops()
IllegalArgumentException
 if the endpoints are unordered and the graph is directed Since:

removeNode
@CanIgnoreReturnValue boolean removeNode(N node)
Removesnode
if it is present; all edges incident tonode
will also be removed. Returns:
true
if the network was modified as a result of this call

removeEdge
@CanIgnoreReturnValue boolean removeEdge(E edge)
Removesedge
from this network, if it is present. Returns:
true
if the network was modified as a result of this call
