public class SolverResult
extends Object

Container for storing performance metrics computed by queueing network solvers.

This class holds both steady-state and transient performance results including queue lengths, utilizations, response times, throughputs, and arrival rates. Results are organized as matrices with dimensions [stations x classes] for station-level metrics and [1 x classes] for system-level metrics.

For solver-specific results, create separate classes (e.g., SolverFluidResult).
