	// updated at end of SetBlockAndValidators
	LastBlockHeight int // Genesis state has this set to 0.  So, Block(H=0) does not exist.
	LastBlockID     types.BlockID
	LastBlockTime   time.Time

}

NOTE: not goroutine-safe.

func GetState added in v0.8.0

func GetState(stateDB dbm.DB, genesisFile string) *State

Load the most recent state from "state" db, or create a new one (and save) from genesis.

func LoadState

func LoadState(db dbm.DB) *State

func MakeGenesisState

func MakeGenesisState(db dbm.DB, genDoc *types.GenesisDoc) *State

MakeGenesisState creates state from types.GenesisDoc.

Used in tests.

func MakeGenesisStateFromFile

func MakeGenesisStateFromFile(db dbm.DB, genDocFile string) *State

MakeGenesisStateFromFile reads and unmarshals state from the given file.

Used during replay and in tests.

func (*State) ApplyBlock added in v0.8.0

func (s *State) ApplyBlock(eventCache types.Fireable, proxyAppConn proxy.AppConnConsensus,
	block *types.Block, partsHeader types.PartSetHeader, mempool types.Mempool) error

Validate, execute, and commit block against app, save block and state

func (*State) Bytes added in v0.8.0

func (s *State) Bytes() []byte

func (*State) CommitStateUpdateMempool added in v0.8.0

func (s *State) CommitStateUpdateMempool(proxyAppConn proxy.AppConnConsensus, block *types.Block, mempool types.Mempool) error

mempool must be locked during commit and update because state is typically reset on Commit and old txs must be replayed against committed state before new txs are run in the mempool, lest they be invalid

func (*State) Copy

func (s *State) Copy() *State

func (*State) Equals added in v0.8.0

func (s *State) Equals(s2 *State) bool

func (*State) Save

func (s *State) Save()

func (*State) SaveABCIResponses added in v0.9.1

func (s *State) SaveABCIResponses(abciResponses *ABCIResponses)

Sets the ABCIResponses in the state and writes them to disk in case we crash after app.Commit and before s.Save()

func (*State) SetBlockAndValidators added in v0.8.0

func (s *State) SetBlockAndValidators(header *types.Header, blockPartsHeader types.PartSetHeader, abciResponses *ABCIResponses)

Mutate state variables to match block and validators after running EndBlock
