}

type CommitStateDB 

type CommitStateDB struct {
	// contains filtered or unexported fields
}

func NewCommitStateDB 

func NewCommitStateDB(ak auth.AccountKeeper, storageKey, codeKey sdk.StoreKey) *CommitStateDB

NewCommitStateDB returns a reference to a newly initialized CommitStateDB which implements Geth's state.StateDB interface.

CONTRACT: Stores used for state must be cache-wrapped as the ordering of the key/value space matters in determining the merkle root. func NewCommitStateDB(ctx sdk.Context, ak auth.AccountKeeper, storageKey, codeKey sdk.StoreKey) *CommitStateDB {

func NewStateDB 

func NewStateDB(db *CommitStateDB) *CommitStateDB

func (*CommitStateDB) AddBalance 

func (csdb *CommitStateDB) AddBalance(addr sdk.AccAddress, amount *big.Int)

AddBalance adds amount to the account associated with addr.

func (*CommitStateDB) AddLog 

func (csdb *CommitStateDB) AddLog(log *Log)

AddLog adds a new log to the state and sets the log metadata from the state.

func (*CommitStateDB) AddPreimage 

func (csdb *CommitStateDB) AddPreimage(hash sdk.Hash, preimage []byte)

AddPreimage records a SHA3 preimage seen by the VM.

func (*CommitStateDB) AddRefund 

func (csdb *CommitStateDB) AddRefund(gas uint64)

AddRefund adds gas to the refund counter.

func (*CommitStateDB) BlockHash 

func (csdb *CommitStateDB) BlockHash() sdk.Hash

BlockHash returns the current block hash set by Prepare.

func (*CommitStateDB) ClearStateObjects 

func (csdb *CommitStateDB) ClearStateObjects()

ClearStateObjects clears cache of state objects to handle account changes outside of the EVM

func (*CommitStateDB) Commit 

func (csdb *CommitStateDB) Commit(deleteEmptyObjects bool) (root sdk.Hash, err error)

Commit writes the state to the appropriate KVStores. For each state object in the cache, it will either be removed, or have it's code set and/or it's state (storage) updated. In addition, the state object (account) itself will be written. Finally, the root hash (version) will be returned.

func (*CommitStateDB) Copy 

func (csdb *CommitStateDB) Copy() *CommitStateDB

Copy creates a deep, independent copy of the state.

NOTE: Snapshots of the copied state cannot be applied to the copy.

func (*CommitStateDB) CreateAccount 

func (csdb *CommitStateDB) CreateAccount(addr sdk.AccAddress)

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 Ether doesn't disappear.

func (*CommitStateDB) Database 

func (csdb *CommitStateDB) Database() ethstate.Database

Database retrieves the low level database supporting the lower level trie ops. It is not used in Ethermint, so it returns nil.

func (*CommitStateDB) Empty 

func (csdb *CommitStateDB) Empty(addr sdk.AccAddress) bool

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

func (*CommitStateDB) Error 

func (csdb *CommitStateDB) Error() error

Error returns the first non-nil error the StateDB encountered.

func (*CommitStateDB) Exist 

func (csdb *CommitStateDB) Exist(addr sdk.AccAddress) bool

Exist reports whether the given account address exists in the state. Notably, this also returns true for suicided accounts.

func (csdb *CommitStateDB) Finalise(deleteEmptyObjects bool)

Finalise finalizes the state objects (accounts) state by setting their state, removing the csdb destructed objects and clearing the journal as well as the refunds.

func (*CommitStateDB) IntermediateRoot 

func (csdb *CommitStateDB) IntermediateRoot(deleteEmptyObjects bool) sdk.Hash

IntermediateRoot returns the current root hash of the state. It is called in between transactions to get the root hash that goes into transaction receipts.
