compare

public int compare(Subspace<?> s1,
                   Subspace<?> s2)

Compares the two specified subspaces for order. If the two subspaces have different dimensionalities a negative integer or a positive integer will be returned if the dimensionality of the first subspace is less than or greater than the dimensionality of the second subspace. Otherwise the comparison works as follows: Let d1 and d2 be the first occurrences of pairwise unequal dimensions in the specified subspaces. Then a negative integer or a positive integer will be returned if d1 is less than or greater than d2. Otherwise the two subspaces have equal dimensions and zero will be returned.
