Class TreeLayout.NormalizedPosition

java.lang.Object

java.awt.geom.Point2D

org.abego.treelayout.TreeLayout.NormalizedPosition

All Implemented Interfaces:

java.lang.Cloneable

Enclosing class:

TreeLayout<TreeNode>

private class TreeLayout.NormalizedPosition
extends java.awt.geom.Point2D

The algorithm calculates the position starting with the root at 0. I.e. the left children will get negative positions. However we want the result to be normalized to (0,0).

TreeLayout.NormalizedPosition will normalize the position (given relative to the root position), taking the current bounds into account. This way the left most node bounds will start at x = 0, the top most node bounds at y = 0.
