All Implemented Interfaces:

GraphLayoutAttrConsumer, NodePositioningPolicy

public class SimplisticNodePositioningPolicy

extends javautils.collections.Algs

implements NodePositioningPolicy

Calculates coordinates of all nodes in a graph. The y-coordinate of each rank is shared by all nodes in the rank, and is simply the sum of y-coordinate of the previous rank, the minimum vertical gap, half of the ranks height and half of the previous ranks height. The y-coordinate of the first rank of the ranking is half of the ranks height.

The x-coordinate of a node is calculated similarly: it is a sum of the x-coordinate of the previous node in the rank, the minimum horizontal gap, half of the width of the previous node in the rank, and half of the current nodes width. The x-coordinate of the first node of each rank is half of the ranks width.
