All Implemented Interfaces:

Layouter, LayoutStage

public class LabelLayoutDataRefinement

extends AbstractLayoutStage

A layout stage that improves the placement of edge labels. This layout stage expects that its core layouter calculates initial edge label layout data bound to the data provider key LabelLayoutKeys.EDGE_LABEL_LAYOUT_KEY. Next this stage tries to improve the position of the labels in respect to the preferred placement specifier of the labels.
