public class IlvUniformLengthEdgesLayoutLinkProperty extends IlvBasicLinkStyleLayoutLinkProperty
IlvUniformLengthEdgesLayoutLinkProperty
allows
you to store the settings of an instance of
IlvUniformLengthEdgesLayout
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.
