Detailed Description

The class Graph is the interface of a Graph in the Tulip Library.

There are a few principles to know when working with a Tulip Graph.

Directed Every edge is directed in a Tulip Graph. You can choose to ignore this, but every edge has a source and destination.

Inheritance

Subgraphs inherit from their parent graph. This is true of nodes and edges; every node and edge in a subgraph also exists in each of its parent graphs. This is also true of properties; every property in a graph exist in all of its subgraphs, except if it has been replaced by a local property.

For instance, ig you have the following graph hierarchy: root / \ A B

Every node in A is in root, and every node in B is in root. Nodes can be in A and root but not B; or in B and root but not A.

For instance, imagine a graph. You want to compare it to its Delaunay triangulation. You need to create a subgraph that is a clone of the original (say this is A) to keep the original graph, and another copy (say this one is B) on which you will perform the delaunay triangulation.

B will have none of the original edges, and A will have only the original edges.

As for properties; let's imagine the same graph hierarchy. You want to compare two different layouts on the same graph. You need to create two clone subgraphs, on each you make the 'viewLayout' property local. This results in A and B having different values for the layout, but everything else in common. You then can apply two different algorithms on A and B (e.g. Bubble Tree and Tree Radial).

Meta Nodes A meta node is a node representing a subgraph of the current graph.

Undo Redo The Tulip Graph object supports for undo and redo of modifications. *The operations affect the whole graph hierarchy, and cannot be limited to a subgraph.

Member Function Documentation

virtual Graph* tlp::Graph::addCloneSubGraph ( std::string name = "unnamed" )

virtual

Creates and returns a subgraph of this graph that contains all its elements.

Parameters

name	The name of the newly created subgraph. Defaults to "unnamed".

Returns: :Graph* The newly created clone subgraph.

virtual edge tlp::Graph::addEdge	(	const node	source,
		const node	target
	)

pure virtual

Adds a new edge in the graph This edge is also added in all the super-graph of the graph.

Parameters

source	The source of the edge.
target	The target of the edge.

Returns: The newly added edge.

See Also: addEdges() to add multiple edges at once.

virtual void tlp::Graph::addEdge ( const edge e )

pure virtual

Adds an existing edge in the graph. This edge is also added in all the ancestor graphs. The edge must be an element of the graph hierarchy, thus it must be an element of the root graph.

Warning: Using this method on the root graph will display a warning on the console.

Parameters

e	The edge to add to this subgraph.

See Also: addEgdes() to add more than one edge at once.; addNode() to add nodes.

virtual void tlp::Graph::addEdges	(	const std::vector< std::pair< node, node > > &	edges,
		std::vector< edge > &	addedEdges
	)

pure virtual

Adds new edges in the graph and returns them the addedEdges vector. The new edges are also added in all the graph ancestors.

Warning: If the edges vector contains a node that does not belong to this graph, undefined behavior will ensue.

Parameters

edges	A vector describing between which nodes to add edges. The first element of the pair is the source, the second is the destination.
addedEdges	The newly added edges. This vector is cleared before being filled.

virtual void tlp::Graph::addEdges ( Iterator< edge > * edges )

pure virtual

Adds existing edges in the graph. The edges are also added in all the ancestor graphs. The added edges must be elements of the graph hierarchy, thus they must be elements of the root graph.

Warning: Using this method on the root graph will display a warning on the console.; The graph does not take ownership of the iterator.

Parameters

edges The edges to add on this subgraph.

virtual void tlp::Graph::addLocalProperty	(	const std::string &	name,
		PropertyInterface *	prop
	)

pure virtual

Adds a property to the graph. The graph takes ownership of the property. If you want to delete it, use Graph::delLocalProperty().

Parameters

name	The unique identifier of the property.
prop	The property to add.

virtual node tlp::Graph::addNode ( )

pure virtual

Adds a new node in the graph and returns it. This node is also added in all the ancestor graphs.

See Also: addNodes() if you want to add more than one node.

Examples:: clique_import/cliqueimport.cpp.

virtual void tlp::Graph::addNode ( const node n )

pure virtual

Adds an existing node in the graph. This node is also added in all the ancestor graphs. This node must exists in the graph hierarchy (which means it must exist in the root graph). You cannot add a node to the root graph this way (as it must already be an element of the root graph).

Warning: Using this method on the root graph will display a warning on the console.

Parameters

n	The node to add to a subgraph. This node must exist in the root graph.

See Also: addNode() to add a new node to a graph.

virtual void tlp::Graph::addNodes	(	unsigned int	nbNodes,
		std::vector< node > &	addedNodes
	)

pure virtual

Adds new nodes in the graph and returns them in the addedNodes vector. The new nodes are also added in all the ancestor graphs.

Parameters

nbNodes	The number of nodes to add.
addedNodes	The newly added nodes. This vector is cleared before being filled.

See Also: addNode() to add a single node.

virtual void tlp::Graph::addNodes ( Iterator< node > * nodes )

pure virtual

Adds existing nodes in the graph. The nodes are also added in all the ancestor graphs. as with addNode(const tlp::node), the nodes must exist in the graph hierarchy and thus exist in the root graph, and node cannot be added this way to the root graph.

Warning: Using this method on the root graph will display a warning on the console.; The graph does not take ownership of the Iterator.

Parameters

nodes An iterator over nodes to add to this subgraph. The graph does not takes ownership of this iterator.

virtual Graph* tlp::Graph::addSubGraph	(	BooleanProperty *	selection = `NULL`,
		std::string	name = `"unnamed"`
	)

pure virtual

Creates and returns a new sub-graph of this graph.

If a BooleanProperty is provided, all the nodes and edges for which it is true will be added to the subgraph. If none is provided, then the subgraph will be empty.

The id parameter should only be provided if you know exactly what you are doing; as Tulip will manage the subgraphs IDs when left to 0. It is only used by the Graph loading as subgraphs ids are preserved when saving/loading a Graph.

Parameters

selection	The elements to add to the new subgraph. Defaults to 0.
name	The name of the newly created subgraph. Defaults to "unnamed".

Returns: :Graph* The newly created subgraph.

Graph* tlp::Graph::addSubGraph ( std::string name )

Creates and returns a new named sub-graph of this graph.

		std::string &	errorMessage,
		DataSet *	dataSet = `NULL`,
		PluginProgress *	progress = `NULL`
	)

refer to its documentation

use buildDefaultDataSet on the plugin object if you have an instance of it

call getPluginParameters() with the name of the plugin on the PluginLister

If an error occurs, a message describing the error should be stored in errorMessage.

Parameters

algorithm	The algorithm to apply.
errorMessage	A string that will be modified to contain an error message should an error occur.
dataSet	The parameters to the algorithm. Defaults to NULL.
progress	A PluginProgress to report the progress of the operation, as well as final state. Defaults to NULL.

Returns: bool Whether the algorithm was successfully applied.

bool tlp::Graph::applyPropertyAlgorithm	(	const std::string &	algorithm,
		PropertyInterface *	result,
		std::string &	errorMessage,
		PluginProgress *	progress = `NULL`,
		DataSet *	parameters = `NULL`
	)

Runs a plugin on the graph, whose result is a property.

Parameters

algorithm	The name of the plugin to run.
result	The property in which to put the results. All previous values will be erased.
errorMessage	Stores the error message if the plugin fails.
progress	A means of feedback during the plugin execution. Some plugins support being stopped or cancelled through this.
parameters	The parameters of the algorithm. Some algorithms use this DataSet to output some additional informations.

Returns: Whether the plugin executed successfully or not. If not, check the error message.

See Also: PluginLister::getPluginParameters() to retrieve the list of default parameters for the pligin.

bool tlp::Graph::attributeExist ( const std::string & name )

Saves the current state of the whole graph hierarchy and allows to revert to this state later on, using pop(). All modifications except those altering the ordering of the edges will be undone.

This allows to undo/redo modifications on a graph. This is mostly useful from a user interface point of view, but some algorithms use this mechanism to clean up before finishing. For instance:

Graph* graph = tlp::newGraph();
DoubleProperty* prop = graph->getProperty<DoubleProperty>("metric");
string errorMessage;
//our super metric stuff we want to kee
DoubleProperty* superProperty = graph->getProperty<DoubleProperty>("superStuff");
vector<PropertyInterface*> propertiesToKeep;
propertiesToKeep.push_back(superProperty);
//apply some metric
graph->applyPropertyAlgorithm("Degree", prop, errorMessage);
// save this state to be able to revert to it later
//however we do not want to allow to unpop(), which would go forward again to the state where prop contains 'Depth'.
//this saves some memory.
//Also we always want to keep the value of our super property, so we pass it in the collection of properties to leave unaffected by the pop().
graph->push(false, propertiesToKeep);
//compute the quality of this metric, or whatever makes sense
int degreeQuality = prop->getMax();
//compute another metric
graph->applyPropertyAlgorithm("Depth", prop, errorMessage);
//compute our secret metric, that depends on depth
graph->applyPropertyAlgorithm("MySuperSecretAlgorithm", superProperty, errorMessage);
//compute its quality
int depthQuality = prop->getMax();
//if the degree was better, revert back to the state where its contents were in prop.
if(degreeQuality > depthQuality) {
   //this does not affect superProperty, as we told the system not to consider it when recording modifications to potentially revert.
   graph->pop();
}
//do some stuff using our high quality metric
ColorProperty* color = graph->getProperty("viewColor");
graph->applyPropertyAlgorithm("Color Mapping", color, errorMessage);

Parameters

unpopAllowed	Whether or not to allow to re-do the modifications once they are undone.
