Graphs a schema as a UML Activity Diagram using Graphviz.
If given a workflow, the graph will be decorationed with stateful information such as the current node (or nodes.)
Ranks all nodes in a given schema.
Will set the rank
field on each Fountainedge.Node
within the schema.
Useful for determining backward and forward directions between two nodes. If the rank of the out edge node is less than the current node, then the direction is backwards. Otherwise, if greater, then the direction is forwards.
dot
creates hierarchical
or layered drawings of directed graphs. A ranking algorithmn is used
to determine this heirarchy. It may be useful to use these ranks
when determining direction in a workflow. Call this function to
calculate ranks per each node.
