This is useful in simulation applications where historical data about component performance are available but do not follow standard distributions (or any application that requires random data generation from an empirical distribution). Also generates data for grouped frequency histograms based on the input file. ValueServer -- a wrapper for RandomData and EmpiricalDistribution that generates values in each of the following modes: * DIGEST_MODE -- uses an empirical distribution * REPLAY_MODE -- replays data from an input file * UNIFORM_MODE -- generates uniformly distributed random values * EXPONENTIAL_MODE -- generates exponentially distributed random values * GAUSSIAN_MODE -- generates Gaussian distributed random values * CONSTANT_MODE -- returns the same value every time. Attaching tar with interface, implementation, test classes and a test data file. The test data file needs to go in src/test/.../math --------------------------------------------------------------------- To unsubscribe, e-mail: commons-dev-unsubscribe@jakarta.apache.org For additional commands, e-mail: commons-dev-help@jakarta.apache.org
