public class IltLinkLayoutLinkProperty extends IlvGraphLayoutLinkProperty
IltLinkLayoutLinkProperty
allows you to store
the settings of an instance of IltLinkLayout
for an individual link as a named property in the link.
This is used by
IlvGrapherAdapter.saveParametersToNamedProperties(IlvGraphLayout, boolean)
which is an auxiliary to be used before
IlvManager.write(IlvOutputStream)
if you
want to store layout parameter settings in .ivl
files.
