Function Documentation

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

Appends the selected part of the graph inG (properties, nodes and edges) into the graph outG. If no selection is done (inSel=NULL), 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.

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

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	The 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 NULL.

Returns

bool Whether the export was successfull or not.

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

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 NULL 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 NULL.
newGraph	The graph to import the data into. This can be usefull to import data into a subgraph. Defaults to NULL.

Returns

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

Examples:

clique_import/cliqueimport.cpp.

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

Loads a graph in the tlp format from a file (extension can be .tlp or .tlp.gz). This function uses the "TLP Import" import plugin, and will fail if it is not loaded (By default this plugin is linked into the library and should be loaded).

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

Parameters

filename

The file in tlp format to parse.

Returns

:Graph* The imported Graph, NULL if the import failed.

Examples:

graph_display/graph_display.cpp.

Graph* tlp::newCloneSubGraph	(	Graph *	graph,
		std::string	name = "unnamed"
	)

Creates and returns a subgraph of the graph that is equal to root (a clone subgraph).

Deprecated:

this function should not be used anymore, please use Graph::addCloneSubGraph() instead.

Parameters

graph	The Graph on which to create a clone subgraph.
name	The name of the newly created subgraph. Defaults to "unnamed".

Returns

:Graph* The newly created clone subgraph.

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.

Graph* tlp::newSubGraph	(	Graph *	graph,
		std::string	name = "unnamed"
	)

Creates and returns an empty subgraph of the given graph.

Deprecated:

this function should not be used anymore, please use Graph::addSubGraph() instead.

Parameters

graph	The graph to add an empty subgraph to.
name	The name of the new subgraph. Defaults to "unnamed".

Returns

:Graph* The newly created subgraph.

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

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

Warning

The selection is extended to all selected edge ends.

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

Saves the corresponding root graph and all its subgraphs to a file using the tlp format. Extension of the file can be either .tlp (human-readable text file) or .tlp.gz (gzipped text file).

This function checks the file name for the '.gz' extension and uses a compressed output if found.

This function uses the "TLP Import" export plugin, and will fail if it is not loaded (by default this plugin is linked into the library and should be loaded).

Parameters

graph	the graph to save.
filename	the file to save the graph to.

Returns

bool Whether the export was successfull or not.
