Graphs.loadgraph
— Methodloadgraph(file, gname="graph", format=LGFormat())
Read a graph named gname
from file
in the format format
.
Implementation Notes
gname
is graph-format dependent and is only used if the file contains multiple graphs; if the file format does not support multiple graphs, this value is ignored. The default value may change in the future.
Graphs.loadgraphs
— Methodloadgraphs(file, format=LGFormat())
Load multiple graphs from file
in the format format
. Return a dictionary mapping graph name to graph.
Implementation Notes
For unnamed graphs the default name "graph" will be used. This default may change in the future.
Graphs.savegraph
— Methodsavegraph(file, g, gname="graph", format=LGFormat)
Saves a graph g
with name gname
to file
in the format format
. Return the number of graphs written.
Implementation Notes
The default graph name assigned to gname
may change in the future.
Graphs.savegraph
— Methodsavegraph(file, d, format=LGFormat())
Save a dictionary d
of graphname => graph
to file
in the format format
. Return the number of graphs written.
Examples
julia> using Graphs
julia> g1 = SimpleGraph(5,8)
{5, 8} undirected simple Int64 graph
julia> g2 = SimpleGraph(7,10)
{7, 10} undirected simple Int64 graph
julia> d = Dict("graph_1" => g1, "graph_2" => g2);
julia> savegraph("myfile.txt", d, LGFormat())
2
Implementation Notes
Will only work if the file format supports multiple graph types.
Graphs.loadlg_mult
— Methodloadlg_mult(io)
Return a dictionary of (name=>graph) loaded from IO stream io
.
Graphs.savelg
— Methodsavelg(io, g, gname)
Write a graph g
with name gname
in a proprietary format to the IO stream designated by io
. Return 1 (number of graphs written).
Graphs.savelg_mult
— Methodsavelg_mult(io, graphs)
Write a dictionary of (name=>graph) to an IO stream io
, with default GZip
compression. Return number of graphs written.
