public Graph.Edge getEdge()
Traverser
Edge
which was traversed to get to
the last node returned by next()
, or
null
if no Edge
was traversed. This
call can be made only if remove()
or removeEdge()
has not been called after the last
call to next()
.
getEdge
in interface Traverser
Edge
which was traversed to get to
the last node returned by next()
, or
null
if no Edge
was traversed.public void removeEdge()
Traverser
Graph
the
Edge
that would be returned by getEdge()
(optional operation). If no Edge
was
traversed (as in the root of a breadth-first search), this
method throws a IllegalStateException
. This
method can be called only once per call to next()
. The behavior of a traverser is unspecified if the
underlying graph structure is modified while the traversal is
in progress in any way other than by calling this method or
remove()
.
