Hi all,
Is this expected behavior? It was surprising to me. On 0.4.0-dev+1745,
pulled today, but I had noticed it previously.
julia> using Graphs
# make a graph and add an edge...
julia> g1 = graph([1, 2], Edge{Int}[])
Directed Graph (2 vertices, 0 edges)
julia> add_edge!(g1, 1, 2)
edge [1]: 1 -- 2
julia> edges(g1)
1-element Array{Edge{Int64},1}:
edge [1]: 1 -- 2
# OK, all is well.
# But how about this graph:
julia> g2 = graph([2, 3], Edge{Int}[])
Directed Graph (2 vertices, 0 edges)
julia> add_edge!(g2, 2, 3)
ERROR: BoundsError()
in add_edge! at /Users/canjo/.julia/v0.4/Graphs/src/graph.jl:87
in add_edge! at /Users/canjo/.julia/v0.4/Graphs/src/graph.jl:98
# Despite giving me an error, it did in fact succesfully add the edge:
julia> edges(g2)
1-element Array{Edge{Int64},1}:
edge [1]: 2 -- 3
What's going on here?
thanks, Richard
