Examples of rinde.sim.core.graph.MultiAttributeData

rinde.sim.core.graph.MultiAttributeData
{@link ConnectionData} implementation which allows to associate multipleattributes to a connection (through a {@link HashMap}). There are two "default" supported properties defined: connection length, and maximum speed on a connection. @author Bartosz Michalik @author Rinde van Lon @since 2.0
