Detailed Description

The Thistle::AbstractGraphAlgorithm class provides an abstract base for the implementation of algorithm used to claculate the position of the nodes in a Thistle::GraphView.

Member Function Documentation

void run ( )

pure virtual

The function is pure virtual.

this function is used to calculate the position of Thistle::Node in a Thistle::GraphView. Implement this function to use your own algorithm.

Implemented in GraphAlgorithm.

inline

Sets the position pos to the given index.

This function should be called by the algorithm implemented in the run() function when a position of an index is known.
