Examples of generateSequence()

eas.simulation.spatial.sim2D.marbSimulation.endlAutomat.EndlicherAutomat.generateSequence()
Gibt die zu this gehörende Automatensequenz in der Standardkodierung zurück. @return Die Automatensequenz.
eu.stratosphere.api.java.ExecutionEnvironment.generateSequence()
Creates a new data set that contains a sequence of numbers. The data set will be created in parallel, so there is no guarantee about the oder of the elements. @param from The number to start at (inclusive). @param to The number to stop at (inclusive). @return A DataSet, containing all number in the {@code [from, to]} interval.
