Detailed Description

Class for testing if the graph is a tree.

static void tlp::TreeTest::cleanComputedTree	(	Graph *	graph,
		Graph *	tree
	)		`[static]`

Clean the graph from a tree previously computed with the computeTree method

static Graph* tlp::TreeTest::computeTree	(	Graph *	graph,
		PluginProgress *	pluginProgress = `NULL`
	)		`[static]`

Computes a rooted tree from the graph. The algorithm is the following :

if the graph is a rooted tree, returns the graph
if the graph is a free tree, returns a rooted clone subgraph
if the graph is connected, makes a clone subgraph and returns a rooted spanning tree of that clone
if the graph is not connected, makes a clone subgraph, computes a tree for each of its connected components, adds a simple source and returns the clone.

static bool tlp::TreeTest::isFreeTree ( Graph * graph ) [static]

Returns true if the graph is a topological tree (i.e. if the graph was undirected, there would be no cycle), false otherwise.

static bool tlp::TreeTest::isTree ( Graph * graph ) [static]

Returns true if the graph is a rooted tree (i.e. a graph with one node designated as the root), false otherwise.

static void tlp::TreeTest::makeDirectedTree	(	Graph *	freeTree,
		node	root
	)		`[inline, static]`

Synonymous of the makeRootedTree method.

static void tlp::TreeTest::makeRootedTree	(	Graph *	freeTree,
		node	root
	)		`[static]`

Turns a free tree into a rooted tree.
