I'm trying to generate graph for GStreamer applications where are many nested bins. Each bin have some elements but bin for parent bin looks like any other common element that have pads (sinks and sources). I want to visualize it but in Graphviz I can't generate nested nodes so I have to do it by subgraphs. Unfortunately subgraphs don't have node options like record shape. In my graph each node have record shape but subgraphs can't. Example:
digraph G
{
graph [rankdir = TD]
node [shape = record]
subgraph cluster_player
{
label = "player"
subgraph cluster_bin1
{
label = "bin1"
bin1_sink1 [label = "sink1"]
bin1_sink2 [label = "sink2"]
obj1 [
label = "{ { <sink1> sink1 | <sink2> sink2 } | obj1 | { <src1> src1 | <src2> src2 } }"
]
bin1_src1 [label = "src1"]
bin1_src2 [label = "src2"]
bin1_sink1:s -> obj1:sink1:n []
bin1_sink2:s -> obj1:sink2:n []
obj1:src1:s -> bin1_src1:n []
obj1:src2:s -> bin1_src2:n []
}
bin1_src1:s -> bin2_sink1:n []
bin1_src2:s -> bin2_sink2:n []
subgraph cluster_bin2
{
label = "bin2"
bin2_sink1 [label = "sink1"]
bin2_sink2 [label = "sink2"]
bin2_obj1 [
label = "{ { <sink1> sink1 | <sink2> sink2 } | obj1 | { <src1> src1 } }"
]
bin2_obj2 [
label = "{ { <sink1> sink1 } | obj2 | { <src1> src1 } }"
]
bin2_src1 [label = "src1"]
bin2_sink1:s -> bin2_obj1:sink1:n []
bin2_sink2:s -> bin2_obj1:sink2:n []
bin2_obj1:src1:s -> bin2_obj2:sink1:n []
bin2_obj2:src1:s -> bin2_src1:n []
}
}
}
As You can see now sources and sinks in bins are like normal elements, but i want them to look like records in "obj1". How to do it? If it's impossible maybe there are others languages that will have that function?
