y.layout.hierarchic.incremental
Interface PortConstraintOptimizer

All Known Implementing Classes:

AbstractPortConstraintOptimizer, PCListOptimizer

public interface PortConstraintOptimizer

This interface serves as a callback for HierarchicLayouter after the layering and sequencing phases.

Implementations of this interface may modify the port constraint information via ItemFactory.setTemporaryPortConstraint(y.base.Edge, boolean, y.layout.PortConstraint).

Method Summary

void	optimizeAfterLayering(LayoutGraph graph, Layers layers, LayoutDataProvider ldp, ItemFactory itemFactory) Assigns new temporary port constraints after the layering information has been determined.
void	optimizeAfterSequencing(LayoutGraph graph, Layers layers, LayoutDataProvider ldp, ItemFactory itemFactory) Assigns new temporary port constraints after the sequence of the nodes has been determined.

Method Detail

optimizeAfterLayering

void optimizeAfterLayering(LayoutGraph graph,
                           Layers layers,
                           LayoutDataProvider ldp,
                           ItemFactory itemFactory)

Assigns new temporary port constraints after the layering information has been determined.

Parameters:

graph - the input graph

layers - the given Layers instance

ldp - the LayoutDataProvider containing information about the elements

itemFactory - the ItemFactory to set the temporary port constraints with
