Interface IPortConstraintOptimizer

All Known Implementing Classes:

AbstractPortConstraintOptimizer, PortCandidateOptimizer

public interface IPortConstraintOptimizer

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

Implementations of this interface may modify the port constraint information via IItemFactory.setTemporaryPortConstraint(com.yworks.yfiles.algorithms.Edge, boolean, com.yworks.yfiles.layout.PortConstraint).

Method Summary

Modifier and Type	Method and Description
void	optimizeAfterLayering(LayoutGraph graph, ILayers layers, ILayoutDataProvider ldp, IItemFactory itemFactory) Assigns new temporary port constraints after the layering information has been determined.
void	optimizeAfterSequencing(LayoutGraph graph, ILayers layers, ILayoutDataProvider ldp, IItemFactory itemFactory) Assigns new temporary port constraints after the sequence of the nodes has been determined.

Method Detail

optimizeAfterLayering

void optimizeAfterLayering(LayoutGraph graph,
                           ILayers layers,
                           ILayoutDataProvider ldp,
                           IItemFactory itemFactory)

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

Parameters:

graph - the input graph

layers - the given ILayers instance

ldp - the ILayoutDataProvider containing information about the elements

itemFactory - the IItemFactory to set the temporary port constraints with
