Overview
Beside a human-readable name, layout options are defined by the following properties:
- An ID to identify them.
- A type. One of Boolean, String, Int, Float, Enum, EnumSet (a
Setover a given enumeration), or Object. The types Enum and EnumSet have to be further defined by an enumeration class. The Object type can be constricted to a certain class. - The kinds of graph objects the option applies to. At least one of Parents (nodes that have children, including the diagram root node), Nodes, Edges, Ports, and Labels.
- An optional default value. If an option is not set on an object and if the option does not have a default value,
nullis returned when it is accessed.
For a general introduction on layout options, see the KIML documentation. KLay Layered supports layout options defined by KIML and defines additional custom layout options.
