func (*StateDB) SubRefund 

func (self *StateDB) SubRefund(gas uint64)

SubRefund removes gas from the refund counter. This method will panic if the refund counter goes below zero

func (*StateDB) SubRewardBalance 

func (self *StateDB) SubRewardBalance(addr common.Address, amount *big.Int)

func (*StateDB) SubRewardBalanceByDelegateAddress 

func (self *StateDB) SubRewardBalanceByDelegateAddress(addr common.Address, deleAddress common.Address, amount *big.Int)

func (*StateDB) Suicide 

func (self *StateDB) Suicide(addr common.Address) bool

Suicide marks the given account as suicided. This clears the account balance.

The account's state object is still available until the state is committed, getStateObject will return a non-nil account after Suicide.

func (*StateDB) TX1Trie 

func (self *StateDB) TX1Trie(a common.Address) Trie

TX1Trie returns the TX1 trie of an account. The return value is a copy and is nil for non-existent accounts.

func (*StateDB) TX3Trie 

func (self *StateDB) TX3Trie(a common.Address) Trie

TX3Trie returns the TX3 trie of an account. The return value is a copy and is nil for non-existent accounts.

func (*StateDB) TxIndex 

func (self *StateDB) TxIndex() int

TxIndex returns the current transaction index set by Prepare.

type Storage 

type Storage map[common.Hash]common.Hash

func (Storage) Copy 

func (self Storage) Copy() Storage

func (Storage) String 

func (self Storage) String() (str string)

type Trie 

type Trie interface {
	// GetKey returns the sha3 preimage of a hashed key that was previously used
	// to store a value.

	// TODO(fjl): remove this when SecureTrie is removed
	GetKey([]byte) []byte

	TryGet(key []byte) ([]byte, error)

	// TryUpdate associates key with value in the trie. If value has length zero, any

	// TryDelete removes any existing value for key from the trie. If a node was not
	// found in the database, a trie.MissingNodeError is returned.
	TryDelete(key []byte) error

	// Hash returns the root hash of the trie. It does not write to the database and
	// can be used even if the trie doesn't have one.
	Hash() common.Hash

	// Commit writes all nodes to the trie's memory database, tracking the internal
	// and external (for account tries) references.
	Commit(onleaf trie.LeafCallback) (common.Hash, error)

	// NodeIterator returns an iterator that returns nodes of the trie. Iteration
	// starts at the key after the given start key.
	NodeIterator(startKey []byte) trie.NodeIterator

	// Prove constructs a Merkle proof for key. The result contains all encoded nodes
	// on the path to the value at key. The value itself is also included in the last
	// node and can be retrieved by verifying the proof.
	//
	// If the trie does not contain a value for key, the returned proof contains all
	// nodes of the longest existing prefix of the key (at least the root), ending
	// with the node that proves the absence of the key.
	Prove(key []byte, fromLevel uint, proofDb neatdb.Writer) error
}

Trie is a Ethereum Merkle Patricia trie.
