Method Detail

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 interface DirectedGraph<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 interface DirectedGraph<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 interface DirectedGraph<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 interface DirectedGraph<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.
