NAME

PathGraph

SYNOPSIS

use Graph::PathGraph;

use Graph::PathGraph qw(:all);

DESCRIPTION

PathGraph class provides the following methods:

new, CollapseVertexAndCollectCyclicPaths, DeleteVerticesWithDegreeLessThan, GetCyclicPaths, GetPaths, IsPathGraph, StringifyPathGraph

PathGraph class is derived from Graph class.

METHODS

new
$NewPathGraph = new Graph::PathGraph($Graph);

Using specified Graph, new method creates a new PathGraph object and returns newly created PathGraph object.

Graph is converted into a PathGraph by copying all its vertices and edges without any associated properties data and associating a Path object to each edge containing edge vertex IDs as intial path.

CollapseVertexAndCollectCyclicPaths
$PathGraph->CollapseVertexAndCollectCyclicPaths($VertexID);

Collapses paths around a VertexID by updating paths around the vertex [Ref 31] and associating any resulting cyclic paths to graph as CyclicPaths property name. And returns PathGraph.

DeleteVerticesWithDegreeLessThan
$Return = $PathGraph->DeleteVerticesWithDegreeLessThan($Degree);

Deletes vertices with degree less than Degree from PathGraph and returns PathGraph.

GetCyclicPaths
@CyclicPaths = $PathGraph->GetCyclicPaths();
$NumOfPaths = $PathGraph->GetCyclicPaths();

Returns an array of cyclic Paths associated with edges in PathGraph. In scalar context, number of cyclic paths is returned.

GetPaths
@Paths = $PathGraph->GetPaths();
$NumOfPaths = $PathGraph->GetPaths();

Returns an array of Paths associated with edges in PathGraph. In scalar context, number of paths is returned.

IsPathGraph
$Status = Graph::PathGraph::IsPathGraph($Object);

Returns 1 or 0 based on whether Object is a PathGraph object.

StringifyPathGraph
$String = $PathGraph->StringifyPathGraph();

Returns a string containing information about traversed paths in PathGraph object.
