Method Details

process

public void process(List<List<SquareNode>> clusters)

Converts all the found clusters into grids, if they are valid.

Parameters:

clusters - List of clusters

checkPreconditions

protected boolean checkPreconditions(List<SquareNode> cluster)

Checks basic preconditions. 1) No node may be linked two more than once

processCluster

protected void processCluster(List<SquareNode> cluster)

Converts the cluster into a grid data structure. If its not a grid then nothing happens
