type Database ¶
type Database interface { // OpenTrie opens the main account trie. OpenTrie(root common.Hash) (Trie, error) // OpenStorageTrie opens the storage trie of an account.

func (*ManagedState) GetNonce ¶
func (ms *ManagedState) GetNonce(cointype string, addr common.Address) uint64
GetNonce returns the canonical nonce for the managed or unmanaged account.

HasAccount returns whether the given address is managed or not
func (*ManagedState) NewNonce ¶
func (ms *ManagedState) NewNonce(cointype string, addr common.Address) uint64

func NewNodeIterator(state *StateDB) *NodeIterator
NewNodeIterator creates an post-order state node iterator.
func (*NodeIterator) Next ¶
func (it *NodeIterator) Next() bool
Next moves the iterator to the next node, returning whether there are any further nodes. In case of an internal error this method returns false and sets the Error field to the encountered failure.
type RangeManage ¶ added in v1.1.2
type StateDB ¶
type StateDB struct {
// contains filtered or unexported fields
}
StateDBs within the matrix protocol are used to store anything within the merkle trie. StateDBs take care of caching and storing nested states. It's the general query interface to retrieve: * Contracts * Accounts

AddPreimage records a SHA3 preimage seen by the VM.
func (*StateDB) CommitSaveTx ¶ added in v1.1.1

Copy creates a deep, independent copy of the state. Snapshots of the copied state cannot be applied to the copy.
func (*StateDB) CreateAccount ¶
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:
- sends funds to sha(account ++ (nonce + 1))
- tx_create(sha(account ++ nonce)) (note that this gets the address of 1)
Carrying over the balance ensures that Maner doesn't disappear.
func (*StateDB) Database ¶
Database retrieves the low level database supporting the lower level trie ops.

func (*StateDB) Empty ¶
Empty returns whether the state object is either non-existent or empty according to the EIP161 specification (balance = nonce = code = 0)
