Class and Description
AbstractPortConstraintOptimizer This class is an abstract implementation of the IPortConstraintOptimizer interface that minimizes the effort required to modify the port assignment after the sequencing phase of hierarchic layout algorithm.
AbstractPortConstraintOptimizer.SameLayerData This static class provides information about the same-layer structures created by class AbstractPortConstraintOptimizer.
ComponentArrangementPolicy
DefaultDrawingDistanceCalculator This class is a default IDrawingDistanceCalculator implementation that is used by HierarchicLayoutCore to configure the INodePlacer.
EdgeDataType
EdgeLayoutDescriptor This class is used by HierarchicLayoutCore during the various phases to provide routing details for the edges of the graph.
EdgeRoutingStyle A routing style constant specifying that the edges should be polyline.
GroupAlignmentPolicy A group layering alignment strategy which aligns groups and normal nodes that occupy the same layer to the top with respect to their inner layers.
GroupCompactionPolicy A strategy specifying no horizontal group compaction.
GroupingSupport.IVisitor Visitor interface that can be used to traverse the descendants of a group node.
HierarchicLayoutCore This class arranges graphs in a hierarchic/layered fashion and supports complete re-layout as well as incremental graph layout.
IDrawingDistanceCalculator This interface determines the minimum distances between elements that belong to the same layer.
IEdgeData This interface provides layout information about the edges of the graph during the layout.
IEdgeReverser This interface handles edges that should be reversed during the hierarchic layout process.
IIncrementalHintsFactory This interface provides factory methods for creating incremental hints for the hierarchic layout.
IItemFactory This interface is a factory for creating and destroying helper structures used in the graph during layout.
ILayer This interface describes a single layer in a hierarchic layout.
ILayerConstraint This interface describes a layering constraint.
ILayerConstraintFactory This interface provides methods for creating layering constraints.
ILayeredComponentsMerger This interface merges two ILayers instances whose nodes reside in the same graph.
ILayerer This interface is used by classes capable of generating a layer assignment.
ILayers This interface manages multiple ILayer instances.
ILayoutDataProvider This interface retrieves INodeData and IEdgeData instances for elements in the current layout graph.
IncrementalHintItemMapping Provides different ways to define a mapping from model items to incremental hints for use with HierarchicLayoutData.
INodeData This interface provides layout information about the nodes of the graph during the layout.
INodePlacer This interface is responsible for the assignment of the x-(sequence) and preliminary y-coordinates of the nodes in a hierarchic layout.
IPortAllocator This interface is responsible for assigning port coordinates to the adjacent edges of each node of the graph.
IPortConstraintOptimizer This interface serves as a callback for HierarchicLayoutCore after the layering and sequencing phases.
ISequenceConstraintFactory This interface specifies the general contract for factory classes that can be used to associate sequence constraints with a graph.
ISequencer This interface is used by HierarchicLayoutCore to calculate the order of the nodes within each layer.
