IPortAssignment	A IPortAssignment is used by SeriesParallelLayout for determining the locations of the edges' ports at their incident nodes.

Class Summary

Class	Description
DefaultOutEdgeComparator	DefaultOutEdgeComparator is the default implementation for the out-edge comparator used in SeriesParallelLayout.
DefaultPortAssignment	DefaultPortAssignment implements the default port assignment strategy.
EdgeLayoutDescriptor	An EdgeLayoutDescriptor provides routing details for an edge that are considered by SeriesParallelLayout.
SeriesParallelLayout	This layout algorithm arranges series-parallel graphs.
SeriesParallelLayoutData	Specifies custom data for the SeriesParallelLayout.

Enum Summary

Enum	Description
ForkStyle	Fork style specifier that defines that the edges will fork on a node.
PortAssignmentMode
RoutingStyle	Style constant describing a polyline edge style.

Package com.yworks.yfiles.layout.seriesparallel Description

Provides the series-parallel layout algorithm.

It can be applied to series-parallel graphs and produces similar results as the hierarchical layout style but without considering global layers.

Series-parallel graphs are directed graphs with a single source (node without incoming edges) and a single sink (node without outgoing edges) that are built using only the following two rules:

1. Series composition: The source of a subgraph is merged with the sink of a second subgraph.
2. Parallel composition: The sources and sinks of two subgraphs are merged.

The layout algorithm is contained in SeriesParallelLayout.
