Method Detail

centerSideDistance	back to summary
private double centerSideDistance(Direction dir, Bounds cur, Bounds tgt) Computes the side distance from current center to target center. Always positive. This is only used for on-axis nodes.

cornerSideDistance	back to summary
private double cornerSideDistance(Direction dir, Bounds cur, Bounds tgt) Computes the side distance between the closest corners of the current and target. Always positive. This is only used for off-axis nodes.

isOnAxis	back to summary
private boolean isOnAxis(Direction dir, Bounds cur, Bounds tgt)

outDistance	back to summary
private double outDistance(Direction dir, Bounds cur, Bounds tgt) Compute the out-distance to the near edge of the target in the traversal direction. Negative means the near edge is "behind".

select	back to summary
public Node select(Node node, Direction dir, TraversalContext context) Implements com.sun.javafx.scene.traversal.Algorithm.select. Doc from com.sun.javafx.scene.traversal.Algorithm.select. Traverse from owner, in direction dir. Return a the new target Node or null if no suitable target is found. Typically, the implementation of override algorithm handles only parent's direct children and looks like this: 1) Find the nearest parent of the "owner" that is handled by this algorithm (i.e. it's a direct child of the root). 2) select the next node within this direct child using the context.selectInSubtree() and return it 2a) if no such node exists, move to the next direct child in the direction (this is where the different order of direct children is defined) or if direct children are not traversable, the select the first node in the next direct child Annotations @Override
