Compact Disk Layout

This chapter describes the major API changes to the CompactDiskLayout introduced with yFiles for HTML 3.0 and how to migrate from the older version.

As with all major layout algorithms, the CompactDiskLayout no longer inherits from MultiStageLayout, but implements ILayoutAlgorithm directly. The layout stages are now managed by a LayoutStageStack, which can be obtained via the layoutStages property; see Layout Stages and Multi-Stage Layouts for more details.

Changed Default Values and Behavior Changes

Node labels are now considered by default. To change this behavior, set the nodeLabelPlacement property to the desired value. It is now also easier to place the node labels with GenericLabeling by setting the value to GENERIC.

Port placement now takes the specified port candidates into account. The ports are placed in a post-processing step by the PortPlacementStage. Port candidates can be specified via the properties on the sub-data CompactDiskLayoutData.ports. See also the section Ports.
