This graph does not pass the hashCode and equals operations through to the backing graph, but relies on Object's equals and hashCode methods. This graph will be serializable if the backing graph is serializable.

Constructor and Description 

AsUnmodifiableGraph(Graph<V,E> g)
Creates a new unmodifiable graph based on the specified backing graph.

Modifier and Type  Method and Description 

E 
addEdge(V sourceVertex,
V targetVertex)
Creates a new edge in this graph, going from the source vertex to the target vertex, and
returns the created edge.

boolean 
addEdge(V sourceVertex,
V targetVertex,
E e)
Adds the specified edge to this graph, going from the source vertex to the target vertex.

boolean 
addVertex(V v)
Adds the specified vertex to this graph if not already present.

GraphType 
getType()
Get the graph type.

boolean 
removeAllEdges(Collection<? extends E> edges)
Removes all the edges in this graph that are also contained in the specified edge collection.

Set<E> 
removeAllEdges(V sourceVertex,
V targetVertex)
Removes all the edges going from the specified source vertex to the specified target vertex,
and returns a set of all removed edges.

boolean 
removeAllVertices(Collection<? extends V> vertices)
Removes all the vertices in this graph that are also contained in the specified vertex
collection.

boolean 
removeEdge(E e)
Removes the specified edge from the graph.

E 
removeEdge(V sourceVertex,
V targetVertex)
Removes an edge going from source vertex to target vertex, if such vertices and such edge
exist in this graph.

boolean 
removeVertex(V v)
Removes the specified vertex from this graph including all its touching edges if present.

The source and target vertices must already be contained in this graph. If they are not found in graph IllegalArgumentException is thrown.
This method creates the new edge e
using this graph's EdgeFactory
.
For the new edge to be added e
must not be equal to any other edge the
graph (even if the graph allows edgemultiplicity). More formally, the graph must not contain
any edge e2
such that e2.equals(e)
. If such
e2
is found then the newly created edge e
is abandoned, the method leaves
this graph unchanged returns
null
.

graph unchanged and returns false. Some graphs do not allow edgemultiplicity. In
such cases, if the graph already contains an edge from the specified source to the specified
target, than this method does not change the graph and returns
false
. If the edge was added to the graph, returns
