Finds all paths starting at a particular node in a DAG
Finds all paths starting at a particular node in a DAG
WARNING: This is an exponential time algorithm (as any algorithm must be for this problem), but is useful for flattening circuit graph hierarchies. Each path is represented by a Seq[T] of nodes in a traversable order.
- start

- returns
a Map[T,Seq[Seq[T]]] where the value associated with v is the Seq of all paths from start to v

def
reachableFrom(root: T, blacklist: Set[T]): LinkedHashSet[T]
Finds the set of nodes reachable from a particular node, with a blacklist.
Finds the set of nodes reachable from a particular node, with a blacklist. The semantics of adding a node to the blacklist is that any of its inedges will be ignored in the traversal. The
root
node is *not* included in the returned set unless it is possible to reachroot
along a non-trivial path beginning atroot
; i.e., if the graph has a cycle that containsroot
.- root
the start node
- blacklist
list of nodes to stop searching, if encountered
- returns
a Set[T] of nodes reachable from
root
