```
    Description copied from interface: Graph
    
    Adds edge e to this graph such that it connects vertex v1 to v2. Equivalent to addEdge(e, new Pair(v1, v2)). If this graph does not contain v1, v2, or both, implementations may choose to either silently add the vertices to the graph or throw an IllegalArgumentException. If this graph assigns edge types to its edges, the edge type of e will be the default for this graph. See Hypergraph.addEdge() for a listing of possible reasons for failure.
    
    Specified by:
    
    addEdge in interface Graph<V,E>
    
    Parameters:
    
    e - the edge to be added
    
    v1 - the first vertex to be connected

public int degree(V vertex)

    Description copied from interface: Hypergraph
    Returns the number of edges incident to vertex. Special cases of interest:
    - Incident self-loops are counted once.
    - If there is only one edge that connects this vertex to each of its neighbors (and vice versa), then the value returned will also be equal to the number of neighbors that this vertex has (that is, the output of getNeighborCount).
    - If the graph is directed, then the value returned will be the sum of this vertex's indegree (the number of edges whose destination is this vertex) and its outdegree (the number of edges whose source is this vertex), minus the number of incident self-loops (to avoid double-counting).
    Equivalent to getIncidentEdges(vertex).size().

    Parameters:

                  V v2)
```
    Description copied from interface: Hypergraph
    Returns an edge that connects this vertex to v. If this edge is not uniquely defined (that is, if the graph contains more than one edge connecting v1 to v2), any of these edges may be returned. findEdgeSet(v1, v2) may be used to return all such edges. Returns null if either of the following is true:

Returns null if v2 is not connected to v1.

```
public Collection<E> getEdges()
```
    Description copied from interface: Hypergraph
    
    Returns a view of all edges in this graph. In general, this obeys the Collection contract, and therefore makes no guarantees about the ordering of the vertices within the set.

    getEdges in interface Hypergraph<V,E>
    
    Returns:
    
    a Collection view of all edges in this graph

public Collection<E> getEdges(EdgeType edgeType)
```
    Description copied from interface: Hypergraph
    
    Returns the collection of edges in this graph which are of type edge_type.
    
    Specified by:
    
    getEdges in interface Hypergraph<V,E>
    
    Parameters:
    
    edgeType - the type of edges to be returned

    the collection of edges which are of type edge_type, or null if the graph does not accept edges of this type

  - getIncidentCount
```
public int getIncidentCount(E edge)
```
    Description copied from interface: Hypergraph
    
    Returns the number of vertices that are incident to edge. For hyperedges, this can be any nonnegative integer; for edges this must be 2 (or 1 if self-loops are permitted).
    Equivalent to getIncidentVertices(edge).size().
    
    Specified by:
    
    getIncidentCount in interface Hypergraph<V,E>
    
    Parameters:
    
    edge - the edge whose incident vertex count is to be returned
    
    Returns:
    
    the number of vertices that are incident to edge.
  - getIncidentEdges
```
public Collection<E> getIncidentEdges(V vertex)
```
    Description copied from interface: Hypergraph
    
    Returns the collection of edges in this graph which are connected to vertex.
    
    Specified by:
    
    getIncidentEdges in interface Hypergraph<V,E>
    
    Parameters:
    
    vertex - the vertex whose incident edges are to be returned
    
    Returns:
    
    the collection of edges which are connected to vertex, or null if vertex is not present
  - getIncidentVertices
```
public Collection<V> getIncidentVertices(E edge)
```
    Description copied from interface: Hypergraph
    
    Returns the collection of vertices in this graph which are connected to edge. Note that for some graph types there are guarantees about the size of this collection (i.e., some graphs contain edges that have exactly two endpoints, which may or may not be distinct). Implementations for those graph types may provide alternate methods that provide more convenient access to the vertices.
    
    Specified by:
    
    getIncidentVertices in interface Hypergraph<V,E>
    
    Parameters:
    
    edge - the edge whose incident vertices are to be returned
    
    Returns:
    
    the collection of vertices which are connected to edge, or null if edge is not present
  - getNeighborCount
```
public int getNeighborCount(V vertex)
```
    Description copied from interface: Hypergraph
    
    Returns the number of vertices that are adjacent to vertex (that is, the number of vertices that are incident to edges in vertex's incident edge set).
    Equivalent to getNeighbors(vertex).size().
    
    Specified by:
    
    getNeighborCount in interface Hypergraph<V,E>
    
    Parameters:
    
    vertex - the vertex whose neighbor count is to be returned
    
    Returns:
    
    the number of neighboring vertices

```
public Collection<V> getNeighbors(V vertex)
```
    Description copied from interface: Hypergraph
    
    Returns the collection of vertices which are connected to vertex via any edges in this graph. If vertex is connected to itself with a self-loop, then it will be included in the collection returned.
    
    Specified by:
    
    getNeighbors in interface Hypergraph<V,E>
    
    Parameters:
    
    vertex - the vertex whose neighbors are to be returned
    
    Returns:
    
    the collection of vertices which are connected to vertex, or null if vertex is not present
  - getVertexCount

    Description copied from interface: Hypergraph
    
    Returns the number of vertices in this graph.
    
    Specified by:
    
    getVertexCount in interface Hypergraph<V,E>
    
    Returns:
    
    the number of vertices in this graph
  - getVertices
```
public Collection<V> getVertices()
```
    Description copied from interface: Hypergraph
    
    Returns a view of all vertices in this graph. In general, this obeys the Collection contract, and therefore makes no guarantees about the ordering of the vertices within the set.
    
    Specified by:
    
    getVertices in interface Hypergraph<V,E>
    
    Returns:
    
    a Collection view of all vertices in this graph
  - isIncident
```
public boolean isIncident(V vertex,
                          E edge)
```
    Description copied from interface: Hypergraph
    
    Returns true if vertex and edge are incident to each other. Equivalent to getIncidentEdges(vertex).contains(edge) and to getIncidentVertices(edge).contains(vertex).
    
    Specified by:
    
    isIncident in interface Hypergraph<V,E>
    
    Parameters:
    
    vertex - vertex to test
    
    edge - edge to test
    
    Returns:
    
    true if vertex and edge are incident to each other
  - isNeighbor
```
public boolean isNeighbor(V v1,
                          V v2)
```
    Description copied from interface: Hypergraph
    
    Returns true if v1 and v2 share an incident edge. Equivalent to getNeighbors(v1).contains(v2).
    
    Specified by:
    
    isNeighbor in interface Hypergraph<V,E>
    
    Parameters:
    
    v1 - the first vertex to test
    
    v2 - the second vertex to test
    
    Returns:
    
    true if v1 and v2 share an incident edge
  - removeEdge
```
public boolean removeEdge(E edge)
```
    Description copied from interface: Hypergraph
    
    Removes edge from this graph. Fails if edge is null, or is otherwise not an element of this graph.
    
    Specified by:
    
    removeEdge in interface Hypergraph<V,E>
    
    Parameters:
    
    edge - the edge to remove
    
    Returns:
    
    true if the removal is successful, false otherwise
  - removeVertex
```
public boolean removeVertex(V vertex)
```
    Description copied from interface: Hypergraph
    Removes vertex from this graph. As a side effect, removes any edges e incident to vertex if the removal of vertex would cause e to be incident to an illegal number of vertices. (Thus, for example, incident hyperedges are not removed, but incident edges--which must be connected to a vertex at both endpoints--are removed.)
    Fails under the following circumstances:
    - vertex is not an element of this graph
    - vertex is null
    Specified by:
    
    removeVertex in interface Hypergraph<V,E>
    
    Parameters:
    
    vertex - the vertex to remove
    
    Returns:
    
    true if the removal is successful, false otherwise
