predecessors :: (Edge e, Ord n) => Graph e n el nl -> n -> [n] Source #

Direct predecessors of a node, i.e. nodes with an outgoing edge to the queried node.

successors :: (Edge e, Ord n) => Graph e n el nl -> n -> [n] Source #

Direct successors of a node, i.e. nodes with an incoming edge from the queried node.

adjacentEdgeSet :: (Edge e, Ord n) => Graph e n el nl -> n -> Set (e n) Source #

adjacentEdges :: (Edge e, Ord n) => Graph e n el nl -> n -> Set (e n) Source #

Deprecated: Use adjacentEdgeSet instead.

pathExists :: (Edge edge, Ord node) => node -> node -> Graph edge node edgeLabel nodeLabel -> Bool Source #

isConsistent :: (Ord n, Eq el) => Graph DirEdge n el nl -> Bool Source #

Manipulate labels

mapNode :: (nl0 -> nl1) -> Graph e n el nl0 -> Graph e n el nl1 Source #

mapNodeWithKey :: (n -> nl0 -> nl1) -> Graph e n el nl0 -> Graph e n el nl1 Source #

mapEdge :: (el0 -> el1) -> Graph e n el0 nl -> Graph e n el1 nl Source #

mapEdgeWithKey :: (e n -> el0 -> el1) -> Graph e n el0 nl -> Graph e n el1 nl Source #

mapNodeWithInOut :: (Edge e, Ord n) => (InOut e n el nl0 -> nl1) -> Graph e n el nl0 -> Graph e n el nl1 Source #

type InOut e n el nl = ([LabeledEdge e n el], LabeledNode n nl, [LabeledEdge e n el]) Source #

filterEdgeWithKey :: (Edge e, Ord n) => (e n -> el -> Bool) -> Graph e n el nl -> Graph e n el nl Source #

traverseNode :: (Applicative f, Edge e, Ord n) => (nl0 -> f nl1) -> Graph e n el nl0 -> f (Graph e n el nl1) Source #

Same restrictions as in traverse.

traverseEdge :: (Applicative f, Edge e, Ord n) => (el0 -> f el1) -> Graph e n el0 nl -> f (Graph e n el1 nl) Source #

Same restrictions as in traverse.

traverse :: (Applicative f, Edge e, Ord n) => (nl0 -> f nl1) -> (el0 -> f el1) -> Graph e n el0 nl0 -> f (Graph e n el1 nl1) Source #

Don't rely on a particular order of traversal!

Combine graphs

checkedZipWith :: (Edge edge, Ord node) => Caller -> (nodeLabel0 -> nodeLabel1 -> nodeLabel2) -> (edgeLabel0 -> edgeLabel1 -> edgeLabel2) -> Graph edge node edgeLabel0 nodeLabel0 -> Graph edge node edgeLabel1 nodeLabel1 -> Graph edge node edgeLabel2 nodeLabel2 Source #

Node and edge sets must be equal.

union :: (Edge edge, Ord node) => Graph edge node edgeLabel nodeLabel -> Graph edge node edgeLabel nodeLabel -> Graph edge node edgeLabel nodeLabel Source #

The node sets must be disjoint.

Manipulate indices

class Edge edge => Reverse edge Source #

Minimal complete definition

reverseEdge

Instances
Reverse DirEdge Source # 
Instance details

Defined in Data.Graph.Comfort

Methods

reverseEdge :: DirEdge node -> DirEdge node Source #

reverse :: (Reverse e, Ord n) => Graph e n el nl -> Graph e n el nl Source #

reverseEdge :: Reverse edge => edge node -> edge node Source #

mapKeys :: (Edge edge1, Ord node0, Ord node1) => (node0 -> node1) -> (edge0 node0 -> edge1 node1) -> Graph edge0 node0 edgeLabel nodeLabel -> Graph edge1 node1 edgeLabel nodeLabel Source #

The index map must be an injection, that is, nodes must not collaps. Also the node and edge index maps must be consistent, i.e.

from (edgeMap e) == nodeMap (from e)
to   (edgeMap e) == nodeMap (to   e)

Strictly spoken, we would need the node map only for isolated nodes, but we use it for all nodes for simplicity.

mapMaybeEdgeKeys :: (Edge e1, Ord n) => (e0 n -> Maybe (e1 n)) -> Graph e0 n el nl -> Graph e1 n el nl Source #

You may only use this for filtering edges and use more specialised types as a result. You must not alter source and target nodes of edges.

mapEdgeKeys :: (Edge e1, Ord n) => (e0 n -> e1 n) -> Graph e0 n el nl -> Graph e1 n el nl Source #

Same restrictions as in mapMaybeEdgeKeys.

Insertion and removal

deleteNode :: (Edge e, Ord n) => n -> Graph e n el nl -> Graph e n el nl Source #

Node to be deleted must be contained in the graph.

deleteNodeSet :: (Edge e, Ord n) => Set n -> Graph e n el nl -> Graph e n el nl Source #

Could be implemented more efficiently.

deleteEdge :: (Edge e, Ord n) => e n -> Graph e n el nl -> Graph e n el nl Source #

insertNode :: Ord n => n -> nl -> Graph e n el nl -> Graph e n el nl Source #

In the current implementation existing nodes are replaced with new labels and existing edges are maintained. However, I think we should better have an extra function for this purpose and you should not rely on this behavior.

insertEdge :: (Edge e, Ord n) => e n -> el -> Graph e n el nl -> Graph e n el nl Source #

insertEdgeSet :: (Edge e, Ord n) => Map (e n) el -> Graph e n el nl -> Graph e n el nl Source #

In the current implementation existing edges are replaced with new labels. However, I think we should better have an extra function for this purpose and you should not rely on this behavior. It is an unchecked error if edges between non-existing nodes are inserted.
