Description

A snapshot graph is a graph constructed from the NetSpider database. It reprensents a graph at specific time.

SnapshotGraph

type SnapshotGraph n na la = ([SnapshotNode n na], [SnapshotLink n la]) Source #

The snapshot graph, which is a collection nodes and links.

Since: 0.3.1.0

graphTimestamp :: SnapshotGraph n na la -> Maybe Timestamp Source #

Get the timestamp of the graph. It's the latest timestamp of the nodes and links.

Since: 0.4.3.0

SnapshotNode

data SnapshotNode n na Source #

A node in the snapshot graph.

nodeId :: SnapshotNode n na -> n Source #

isOnBoundary :: SnapshotNode n na -> Bool Source #

This property is True if the node is on the boundary of the query. This means that nodes adjacent to this node may not be included in the query result.

nodeTimestamp :: SnapshotNode n na -> Maybe Timestamp Source #

If the node is not observed yet or isOnBoundary is True, its timestamp is Nothing.

nodeAttributes :: SnapshotNode n na -> Maybe na Source #

If the node is not observed yet or isOnBoundary is True, its node attributes is Nothing.

SnapshotLink

data SnapshotLink n la Source #

A link in the snapshot graph.

SnapshotLink is summary of one or more link observations by different subject nodes. Basically the latest of these observations is used to make SnapshotLink.

type n: node ID.
type la: link attributes.
