predecessors
Description copied from interface:GraphReturns a live view of all nodes in this graph adjacent tonodewhich can be reached by traversingnode's incoming edges against the direction (if any) of the edge.In an undirected graph, this is equivalent to
Graph.adjacentNodes(Object).If
nodeis removed from the graph after this method is called, theSetviewreturned by this method will be invalidated, and will throwIllegalStateExceptionif it is accessed in any way, with the following exceptions:view.equals(view)evaluates totrue(but any other `equals()` expression involvingviewwill throw)hashCode()does not throw- if
nodeis re-added to the graph after having been removed,view's behavior is undefined

successors
Description copied from interface:GraphReturns a live view of all nodes in this graph adjacent tonodewhich can be reached by traversingnode's outgoing edges in the direction (if any) of the edge.In an undirected graph, this is equivalent to
Graph.adjacentNodes(Object).This is not the same as "all nodes reachable from
nodeby following outgoing edges". For that functionality, seeGraphs.reachableNodes(Graph, Object).If
nodeis removed from the graph after this method is called, theSetviewreturned by this method will be invalidated, and will throwIllegalStateExceptionif it is accessed in any way, with the following exceptions:view.equals(view)evaluates totrue(but any other `equals()` expression involvingviewwill throw)hashCode()does not throw- if
nodeis re-added to the graph after having been removed,view's behavior is undefined

incidentEdges
Description copied from interface:BaseGraphReturns a live view of the edges in this graph whose endpoints includenode.This is equal to the union of incoming and outgoing edges.

inDegree
Description copied from interface:BaseGraphReturns the count ofnode's incoming edges (equal topredecessors(node).size()) in a directed graph. In an undirected graph, returns theBaseGraph.degree(Object).If the count is greater than
Integer.MAX_VALUE, returnsInteger.MAX_VALUE. -
outDegree
Description copied from interface:BaseGraphReturns the count ofnode's outgoing edges (equal tosuccessors(node).size()) in a directed graph. In an undirected graph, returns theBaseGraph.degree(Object).If the count is greater than
Integer.MAX_VALUE, returnsInteger.MAX_VALUE. -
hasEdgeConnecting
Description copied from interface:BaseGraphReturns true if there is an edge that directly connectsnodeUtonodeV. This is equivalent tonodes().contains(nodeU) && successors(nodeU).contains(nodeV).In an undirected graph, this is equal to
hasEdgeConnecting(nodeV, nodeU).- Specified by:

hasEdgeConnecting
Description copied from interface:BaseGraphReturns true if there is an edge that directly connectsendpoints(in the order, if any, specified byendpoints). This is equivalent toedges().contains(endpoints).Unlike the other
EndpointPair-accepting methods, this method does not throw if the endpoints are unordered; it simply returns false. This is for consistency with the behavior of(which does not generally throw if the object cannot be present in the collection), and the desire to have this method's behavior be compatible withinvalid reference
