add

public ParameterGrid add(String name,
 double... values)

size

public int size()

combinations

public List<Map<String,Double>> combinations()

All parameter combinations, insertion-ordered and deterministic. Empty for an empty grid, consistent with size() — never a single empty map, which a strategy factory would NPE on.
