public class IlvShortLinkLayoutLinkProperty extends IlvGraphLayoutLinkProperty
IlvShortLinkLayoutLinkProperty
allows you to
store the settings of an instance of IlvShortLinkLayout
for an individual link as a named property in the link. This is used
by IlvGrapherPropertyAdapter.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.IlvGrapherPropertyAdapter.saveParametersToNamedProperties(IlvGraphLayout, boolean)
