Detailed Description

This abstract class describes a basic algorithm plugin.

It inherits on WithParameter and WithDependency for convenience. Basic functionality consists in checking the algorithm can run on the current Graph (e.g. is the graph simple ?), running the algorithm and resetting the algorithm to re-apply it. The algorithm can and should report progress and which task it is performing if it is decomposed in multiple phases (e.g. layouting the graph, coloring it, ...).

Constructor & Destructor Documentation

Algorithm()

tlp::Algorithm::Algorithm ( const PluginContext *  context )

inline

Constructs an algorithm and initializes members from the AlgorithmContext.

Parameters

context

The context this algorithm runs in, containing the graph, a DataSet for the parameters, and a PluginProgress to give feedback to the user about the tasks the algorithm is performing.

Definition at line 55 of file Algorithm.h.

Member Function Documentation

category()

std::string tlp::Algorithm::category ( ) const

inlineoverridevirtual

A string identifier for a plugin used for categorization purposes.

Returns

std::string the category of the plugin.

Implements tlp::Plugin.

Reimplemented in tlp::StringAlgorithm, tlp::SizeAlgorithm, tlp::LayoutAlgorithm, tlp::IntegerAlgorithm, tlp::DoubleAlgorithm, tlp::ColorAlgorithm, tlp::BooleanAlgorithm, and tlp::PropertyAlgorithm.

Definition at line 80 of file Algorithm.h.

check()

virtual bool tlp::Algorithm::check ( std::string &  )

inlinevirtual

Checks whether the algorithm can be applied on this graph or not. If not, the reason why should be reported through the PluginProgress.

Parameters

errorMessage

A string whose value will be modified to an error message, if the check fails.

Returns

bool Whether the plug-in can run on this Graph.

Definition at line 91 of file Algorithm.h.

icon()

std::string tlp::Algorithm::icon ( ) const

inlineoverridevirtual

The icon (preferably a thumbnail) of the plugin.

Returns

std::string the icon path

Reimplemented from tlp::Plugin.

Definition at line 66 of file Algorithm.h.

Here is the call graph for this function:

run()

virtual bool tlp::Algorithm::run ( )

pure virtual

Runs the algorithm. It is a good practice to report progress through the PluginProgress, Even if your algorithm is very fast. Keep in mind that Tulip can handle very large graphs. The PluginProgress should also be used to report errors, if any.

Returns

bool Whether the algorithm execution was successful or not.

Here is the caller graph for this function:

Member Data Documentation

dataSet

DataSet* tlp::Algorithm::dataSet

A DataSet containing parameters for this algorithm, if any. Retrieved from the context at construction.

Definition at line 107 of file Algorithm.h.

graph

Graph* tlp::Algorithm::graph

The graph this algorithm will be run on. Retrieved from the context at construction.

Definition at line 97 of file Algorithm.h.

pluginProgress

PluginProgress* tlp::Algorithm::pluginProgress

A PluginProgress to give feedback to the user, retrieved from the context. It can be a nullptr pointer, so use with caution.

Definition at line 102 of file Algorithm.h.
