Function Documentation

copyToGraph()

void tlp::copyToGraph	(	Graph *	outG,
		const Graph *	inG,
		BooleanProperty *	inSelection = nullptr,
		BooleanProperty *	outSelection = nullptr
	)

Appends the selected part of the graph inG (properties, nodes and edges) into the graph outG. If no selection is done (inSel=nullptr), the whole inG graph is appended. The output selection is used to select the appended nodes & edges

Warning

The input selection is extended to all selected edge ends.

exportGraph()

bool tlp::exportGraph	(	Graph *	graph,
		std::ostream &	outputStream,
		const std::string &	format,
		DataSet &	dataSet,
		PluginProgress *	progress = nullptr
	)

Exports a graph using the specified export plugin with parameters stored in the DataSet.

You determine the destination, whether by using a fstream, or by saving the contents of the stream to the destination of your choice.

Parameters

graph	The graph to export.
outputStream	The stream to export to. Can be a standard ostream, an ofstream, or even a gzipped ostream.
format	The format to use to export the Graph.
dataSet	Parameters to pass to the export plugin (e.g. additional data, options for the format)
progress	A PluginProgress to report the progress of the operation, as well as final state. Defaults to nullptr.

Returns

bool Whether the export was successful or not.

getRootGraphs()

Iterator<Graph *>* tlp::getRootGraphs

(

)

Gets an iterator over the root graphs. That is all the currently existing graphs which have been created using the tlp::newGraph, tlp::loadGraph or tlp::importGraph functions and are the root graphs of an existing graph hierarchy.

Returns

An iterator over all the root graphs. The caller of this function is responsible of the deletion of the returned iterator.

importGraph()

Graph* tlp::importGraph	(	const std::string &	format,
		DataSet &	dataSet,
		PluginProgress *	progress = nullptr,
		Graph *	newGraph = nullptr
	)

Imports a graph using the specified import plugin with the parameters stored in the DataSet.

If no graph is passed, then a new graph will be created. You can pass a graph in order to import data into it. Returns the graph with imported data, or nullptr if the import failed. In this case, the Pluginprogress should have an error that can be displayed.

Parameters

format	The format to use to import the graph.
dataSet	The parameters to pass to the import plugin (file to read, ...)
progress	A PluginProgress to report the progress of the operation, as well as final state. Defaults to nullptr.
newGraph	The graph to import the data into. This can be useful to import data into a subgraph. Defaults to nullptr.

Returns

:Graph* The graph containing the imported data, or nullptr in case of failure.

Examples

clique_import/cliqueimport.cpp.

loadGraph()

Graph* tlp::loadGraph	(	const std::string &	filename,
		tlp::PluginProgress *	progress = nullptr
	)

Loads a graph from a file (extension can be any of the Tulip supported input graph file format).

This function loads a graph serialized in a file trough the available Tulip import plugins. Since Tulip 4.8, the selection of the import plugin is based on the provided filename extension. The import will fail if the selected import plugin is not loaded. The graph file formats that can currently be imported are : TLP (*.tlp, *.tlp.gz, *.tlpz), TLP Binary (*.tlpb, *.tlpb.gz, *.tlpbz), TLP JSON (*.json), Gephi (*.gexf), Pajek (*.net, *.paj), GML (*.gml), Graphviz (*.dot) and UCINET (*.txt)

Before Tulip 4.8 and as a fallback, the function uses the "TLP Import" import plugin (always loaded as it is linked into the tulip-core library).

If the import fails (no such file, parse error, ...) nullptr is returned.

Parameters

filename

the file in one of the supported formats to parse.

Returns

Graph* the imported Graph, nullptr if the import failed.

Examples

graph_display/graph_display.cpp.

newGraph()

Graph* tlp::newGraph

(

)

Creates a new, empty graph.

This is a simple method factory to create a Graph implementation (remember, Graph is only an interface).

This is the recommended way to create a new Graph.

Returns

:Graph* A new, empty graph.

Examples

graph_display/graph_display.cpp.

removeFromGraph()

void tlp::removeFromGraph	(	Graph *	ioG,
		BooleanProperty *	inSelection = nullptr
	)

Removes the selected part of the graph ioG (properties values, nodes and edges). If no selection is done (inSel=nullptr), the whole graph is reset to default value.

Warning

The selection is extended to all selected edge ends.

saveGraph()

bool tlp::saveGraph	(	Graph *	graph,
		const std::string &	filename,
		tlp::PluginProgress *	progress = nullptr,
		tlp::DataSet *	data = nullptr
	)

Saves the corresponding graph to a file (extension can be any of the Tulip supported output graph file format)..

This function serializes the corresponding graph and all its subgraphs (depending on the format) to a file through the available Tulip export plugins. Since Tulip 4.8, the selection of the export plugin is based on the provided filename extension. The export will fail if the selected export plugin is not loaded.

Before Tulip 4.8 and as a fallback, this function uses the "TLP Export" export plugin (always loaded as it is linked into the tulip-core library).

Parameters

graph	the graph to save.
filename	the file to save the graph to.
progress	PluginProgress to report the progress of the operation, as well as final state. Defaults to nullptr.
data	Parameters to pass to the export plugin (e.g. additional data, options for the format)

Returns

bool whether the export was successful or not.
