type RangeManage struct {
	Range byte
	State *StateDB
}

type StateDB 

type StateDB struct {
	// contains filtered or unexported fields

func (self *StateDB) CreateAccount(addr common.Address)

CreateAccount explicitly creates a state object. If a state object with the address already exists the balance is carried over to the new account.

CreateAccount is called during the EVM CREATE operation. The situation might arise that a contract does the following:

  1. sends funds to sha(account ++ (nonce + 1))
  2. tx_create(sha(account ++ nonce)) (note that this gets the address of 1)

Carrying over the balance ensures that Maner doesn't disappear.
