Constants ¶
This section is empty.
Variables ¶
var StartingNonce uint64
The starting nonce determines the default nonce when new accounts are being created.
Functions ¶
This section is empty.
Types ¶
type ManagedState ¶
type ManagedState struct { *StateDB // contains filtered or unexported fields }
func ManageState ¶
func ManageState(statedb *StateDB) *ManagedState
ManagedState returns a new managed state with the statedb as it's backing layer
func (*ManagedState) GetNonce ¶
func (ms *ManagedState) GetNonce(addr common.Address) uint64
GetNonce returns the canonical nonce for the managed or unmanged account
func (*ManagedState) HasAccount ¶
func (ms *ManagedState) HasAccount(addr common.Address) bool
HasAccount returns whether the given address is managed or not
func (*ManagedState) NewNonce ¶
func (ms *ManagedState) NewNonce(addr common.Address) uint64
NewNonce returns the new canonical nonce for the managed account
func (*ManagedState) RemoveNonce ¶
func (ms *ManagedState) RemoveNonce(addr common.Address, n uint64)
RemoveNonce removed the nonce from the managed state and all future pending nonces
func (*ManagedState) SetNonce ¶
func (ms *ManagedState) SetNonce(addr common.Address, nonce uint64)
SetNonce sets the new canonical nonce for the managed state
func (*ManagedState) SetState ¶
func (ms *ManagedState) SetState(statedb *StateDB)
SetState sets the backing layer of the managed state
type StateDB ¶
type StateDB struct {
// contains filtered or unexported fields
}
StateDBs within the ethereum 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
func (*StateDB) CommitBatch ¶
CommitBatch commits all state changes to a write batch but does not execute the batch. It is used to validate state changes against the root hash stored in a block.
func (*StateDB) CreateStateObject ¶
func (self *StateDB) CreateStateObject(addr common.Address) *StateObject
Creates creates a new state object and takes ownership. This is different from "NewStateObject"
func (*StateDB) DeleteStateObject ¶
func (self *StateDB) DeleteStateObject(stateObject *StateObject)
Delete the given state object and delete it from the state trie
func (*StateDB) GetBalance ¶
Retrieve the balance from the given address or 0 if object not found
func (*StateDB) GetOrNewStateObject ¶
func (self *StateDB) GetOrNewStateObject(addr common.Address) *StateObject
Retrieve a state object or create a new state object if nil
func (*StateDB) GetStateObject ¶
func (self *StateDB) GetStateObject(addr common.Address) (stateObject *StateObject)
Retrieve a state object given my the address. Nil if not found
func (*StateDB) IntermediateRoot ¶
IntermediateRoot computes the current root hash of the state trie. It is called in between transactions to get the root hash that goes into transaction receipts.
func (*StateDB) SetStateObject ¶
func (self *StateDB) SetStateObject(object *StateObject)
func (*StateDB) UpdateStateObject ¶
func (self *StateDB) UpdateStateObject(stateObject *StateObject)
Update the given state object and apply it to state trie
type StateObject ¶
type StateObject struct {
// contains filtered or unexported fields
}
func NewStateObject ¶
func NewStateObject(address common.Address, db ethdb.Database) *StateObject
func NewStateObjectFromBytes ¶
func (*StateObject) AddBalance ¶
func (c *StateObject) AddBalance(amount *big.Int)
func (*StateObject) Address ¶
func (c *StateObject) Address() common.Address
Returns the address of the contract/account
func (*StateObject) Balance ¶
func (self *StateObject) Balance() *big.Int
func (*StateObject) Code ¶
func (self *StateObject) Code() []byte
func (*StateObject) CodeHash ¶
func (c *StateObject) CodeHash() common.Bytes
func (*StateObject) Copy ¶
func (self *StateObject) Copy() *StateObject
func (*StateObject) CreateOutputForDiff ¶
func (self *StateObject) CreateOutputForDiff()
Debug stuff
func (*StateObject) EachStorage ¶
func (self *StateObject) EachStorage(cb func(key, value []byte))
func (*StateObject) MarkForDeletion ¶
func (self *StateObject) MarkForDeletion()
func (*StateObject) Nonce ¶
func (self *StateObject) Nonce() uint64
func (*StateObject) ReturnGas ¶
func (c *StateObject) ReturnGas(gas, price *big.Int)
Return the gas back to the origin. Used by the Virtual machine or Closures
func (*StateObject) RlpEncode ¶
func (c *StateObject) RlpEncode() []byte
State object encoding methods
func (*StateObject) Root ¶
func (self *StateObject) Root() []byte
func (*StateObject) SetBalance ¶
func (c *StateObject) SetBalance(amount *big.Int)
func (*StateObject) SetCode ¶
func (self *StateObject) SetCode(code []byte)
func (*StateObject) SetNonce ¶
func (self *StateObject) SetNonce(nonce uint64)
func (*StateObject) SetState ¶
func (self *StateObject) SetState(k, value common.Hash)
func (*StateObject) St ¶
func (c *StateObject) St() Storage
func (*StateObject) Storage ¶
func (self *StateObject) Storage() Storage

func (*StateObject) Update ¶
func (self *StateObject) Update()
Update updates the current cached storage to the trie
func (*StateObject) Value ¶
func (self *StateObject) Value() *big.Int
Never called, but must be present to allow StateObject to be used as a vm.Account interface that also satisfies the vm.ContractRef interface. Interfaces are awesome.
type StateSync ¶
StateSync is the main state synchronisation scheduler, which provides yet the unknown state hashes to retrieve, accepts node data associated with said hashes and reconstructs the state database step by step until all is done.
func NewStateSync ¶
NewStateSync create a new state trie download scheduler.
func (*StateSync) Missing ¶
Missing retrieves the known missing nodes from the state trie for retrieval.
type StorageState ¶
Storage change object. Used by the manifest for notifying changes to the sub channels.
