inDegreeOf
public int inDegreeOf(V vertex)
Description copied from interface:DirectedGraph
Returns the "in degree" of the specified vertex. An in degree of a vertex in a directed graph is the number of inward directed edges from that vertex. See http://mathworld.wolfram.com/Indegree.html.- Specified by:
inDegreeOf
in interfaceDirectedGraph<V,E>
- Parameters:
vertex
- vertex whose degree is to be calculated.- Returns:
- the degree of the specified vertex.
-
incomingEdgesOf
public java.util.Set<E> incomingEdgesOf(V vertex)
Description copied from interface:DirectedGraph
Returns a set of all edges incoming into the specified vertex.- Specified by:
incomingEdgesOf
in interfaceDirectedGraph<V,E>
- Parameters:
vertex
- the vertex for which the list of incoming edges to be returned.- Returns:
- a set of all edges incoming into the specified vertex.
-
outDegreeOf
public int outDegreeOf(V vertex)
Description copied from interface:DirectedGraph
Returns the "out degree" of the specified vertex. An out degree of a vertex in a directed graph is the number of outward directed edges from that vertex. See http://mathworld.wolfram.com/Outdegree.html.- Specified by:
outDegreeOf
in interfaceDirectedGraph<V,E>
- Parameters:
vertex
- vertex whose degree is to be calculated.- Returns:
- the degree of the specified vertex.
-
outgoingEdgesOf
public java.util.Set<E> outgoingEdgesOf(V vertex)
Description copied from interface:DirectedGraph
Returns a set of all edges outgoing from the specified vertex.- Specified by:
outgoingEdgesOf
in interfaceDirectedGraph<V,E>
- Parameters:
vertex
- the vertex for which the list of outgoing edges to be returned.- Returns:
- a set of all edges outgoing from the specified vertex.
