public AbstractArchetypeVertex()

Method Detail

getIncidentElements

public java.util.Set getIncidentElements()

Description copied from interface: Element

Returns the set of elements that are incident to this element. For a vertex this corresponds to returning the vertex's incident edges; for an edge this corresponds to returning the edge's incident vertices.

Specified by:

getIncidentElements in interface Element

See Also:

Element.getIncidentElements()

getNeighbors

public java.util.Set getNeighbors()

Description copied from interface: ArchetypeVertex

Returns the set of vertices which are connected to this vertex via edges; each of these vertices should implement ArchetypeVertex. If this vertex is connected to itself with a self-loop, then this vertex will be included in its own neighbor set.

Specified by:

getNeighbors in interface ArchetypeVertex

See Also:

ArchetypeVertex.getNeighbors()

numNeighbors

public int numNeighbors()

Description copied from interface: ArchetypeVertex

Returns the number of neighbors that this vertex has. If the graph is directed, the value returned will be the sum of the number of predecessors and the number of successors that this vertex has.

Specified by:

numNeighbors in interface ArchetypeVertex

See Also:

ArchetypeVertex.numNeighbors()

getIncidentEdges

public java.util.Set getIncidentEdges()

Description copied from interface: ArchetypeVertex

Returns the set of edges which are incident to this vertex. Each of these edges should implement ArchetypeEdge.

Specified by:

getIncidentEdges in interface ArchetypeVertex

See Also:

ArchetypeVertex.getIncidentEdges()

degree

public int degree()

Description copied from interface: ArchetypeVertex

Returns the number of edges incident to this vertex. Special cases of interest:

• 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.
• 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).

Specified by:

degree in interface ArchetypeVertex

Returns:

int the degree of this node

See Also:

ArchetypeVertex.degree()

isNeighborOf

public boolean isNeighborOf(ArchetypeVertex v)

Description copied from interface: ArchetypeVertex

Returns true if the specified vertex v and this vertex are each incident to one or more of the same edges, and false otherwise. The behavior of this method is undefined if v is not an element of this vertex's graph.

Specified by:

isNeighborOf in interface ArchetypeVertex

See Also:

ArchetypeVertex.isNeighborOf(ArchetypeVertex)

isIncident

public boolean isIncident(ArchetypeEdge e)

Description copied from interface: ArchetypeVertex

Returns true if the specified edge e is incident to this vertex, and false otherwise. The behavior of this method is undefined if e is not an element of this vertex's graph.

Specified by:

isIncident in interface ArchetypeVertex

See Also:

ArchetypeVertex.isIncident(ArchetypeEdge)

copy

public ArchetypeVertex copy(ArchetypeGraph g)

Description copied from interface: ArchetypeVertex

Creates a copy of this vertex in graph g. The vertex created will be equivalent to this vertex: given v = this.copy(g), then this.getEquivalentVertex(g) == v, and this.equals(v) == true.

Specified by:

copy in interface ArchetypeVertex

Parameters:

g - the graph in which the copied vertex will be placed

Returns:

the vertex created

See Also:

ArchetypeVertex.copy(edu.uci.ics.jung.graph.ArchetypeGraph)

equals

public boolean equals(java.lang.Object o)

Returns true if o is an instance of ArchetypeVertex that is equivalent to this vertex. Respects the vertex equivalences which are established by copy() and referenced by getEquivalentVertex().

Overrides:

equals in class java.lang.Object

See Also:

Object.equals(java.lang.Object), ArchetypeVertex.getEqualVertex(ArchetypeGraph), ArchetypeVertex.copy(edu.uci.ics.jung.graph.ArchetypeGraph)

getEqualVertex

public ArchetypeVertex getEqualVertex(ArchetypeGraph ag)

Returns the vertex in the specified graph ag that is equivalent to this vertex. If there is no such vertex, or if ag is not an instance of AbstractSparseGraph, returns null.

Specified by:

getEqualVertex in interface ArchetypeVertex

See Also:

ArchetypeVertex.getEqualVertex(ArchetypeGraph)

getEquivalentVertex

public ArchetypeVertex getEquivalentVertex(ArchetypeGraph ag)

Deprecated. As of version 1.4, renamed to getEqualVertex(ag).

Specified by:

getEquivalentVertex in interface ArchetypeVertex

findEdge

public ArchetypeEdge findEdge(ArchetypeVertex v)

Description copied from interface: ArchetypeVertex

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 this vertex to v), any of these edges v may be returned. findEdgeSet(v) may be used to return all such edges. If v is not connected to this vertex, returns null.

Specified by:

findEdge in interface ArchetypeVertex

See Also:

ArchetypeVertex.findEdge(edu.uci.ics.jung.graph.ArchetypeVertex)

findEdgeSet

public java.util.Set findEdgeSet(ArchetypeVertex v)

Description copied from interface: ArchetypeVertex

Returns the set of all edges that connect this vertex with the specified vertex v. findEdge(v) may be used to return a single (arbitrary) element of this set. If v is not connected to this vertex, returns an empty Set.

Specified by:

findEdgeSet in interface ArchetypeVertex

See Also:

ArchetypeVertex.findEdgeSet(edu.uci.ics.jung.graph.ArchetypeVertex)

getNeighbors_internal

protected abstract java.util.Collection getNeighbors_internal()

Returns a set containing all neighbors of this vertex. This is an internal method which is not intended for users.

getEdges_internal

protected abstract java.util.Collection getEdges_internal()

Returns a set containing all the incident edges of this vertex. This is an internal method which is not intended for users.
