public class IlvUniformLengthEdgesLayoutGrapherProperty extends IlvBasicLinkStyleLayoutGrapherProperty
IlvUniformLengthEdgesLayoutGrapherProperty
allows you to store the global settings of an instance of
IlvUniformLengthEdgesLayout
as a named property in the
grapher. This is used by IlvGrapherPropertyAdapter.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.
