Grid Layouts

The class GridLayout represents grid layouts of graphs, which are, e.g., produced by a grid layout algorithm.

The abstract class GridLayoutInfo realizes a generic access to grid layouts. This makes it possible to maintain an implicit representation of the actual grid layout, e.g., the grid layout is produced for a manipulated copy of the graph and the respective implementation of GridLayoutInfo (in this case GraphCopyGLI) knows, how to transform it to a grid layout of the original graph. These classes are used by grid coordinate mappers.

This mechanism is also extended to cluster graphs. The class CGGridLayout represents grid layouts of cluster graphs and CGGridLayoutInfo the corresponding info class. Such info classes are used by the call function of GridCoordinateMapper for cluster graphs.
