Function KeepOdd

key/key_manager.go:100–111

KeepOdd only retains the odd values in the contract.Keyer. Note: The alternating key-values count from zero. Odd values are the "value" in key-value pairs. To avoid confusion, the KeepEven method is intentionally not provided.

(k contract.Keyer)

// key-value pairs. To avoid confusion, the KeepEven method is intentionally not
// provided.

	var (
		spreader = k.Spread()

	)
	for i := range spreader {
		if i%2 == 1 {
			km.Prefixes = append(km.Prefixes, spreader[i])
