Method compare

crypt.go:714–728

compare provides a function to compare object path, each set of sibling objects in one level of the containment hierarchy (all child objects under a storage object) is represented as a red-black tree. The parent object of this set of siblings will have a pointer to the top of this tree.

(left, right string)

// a storage object) is represented as a red-black tree. The parent object of
// this set of siblings will have a pointer to the top of this tree.
func (c *cfb) compare(left, right string) int {

	for Z := int(math.Min(float64(len(L)), float64(len(R)))); i < Z; i++ {
		if j = len(L[i]) - len(R[i]); j != 0 {
			return j

			if L[i] < R[i] {
				return -1
