Class GlobalConstants

java.lang.Object
jline.GlobalConstants
public class GlobalConstants extends Object
Global constants for tolerances and solver configuration.

This class defines system-wide constants used throughout the LINE solver including:

  • Numerical tolerances for convergence checks
  • Special values (infinity, zero threshold)
  • Version information
  • Verbosity settings

The class follows a singleton pattern to ensure consistent configuration across all solver components.
