public class IltLinkLayoutGrapherProperty extends IlvGraphLayoutGrapherProperty
IltLinkLayoutGrapherProperty
allows you to store the global settings of an instance
of IltLinkLayout
as a named property in the grapher. This is used by
IlvGrapherAdapter.saveParametersToNamedProperties(IlvGraphLayout, boolean)
which is an auxiliary to be used before
IlvGrapher.write(IlvOutputStream)
if you
want to store layout parameter settings in .ivl
files.
