如果是子链分片节点，关心txsch和chainHead通道（Header的ShardId和自身的一致）
如果是主链节点，关心的是shardInfo和chainHead通道（Header的ShardId和自身的一致）

Types

type Backend

type Backend interface {
	BlockChain() *core.BlockChain
	TxPool() core.TxPoolIntf
	ShardPool() *qchain.ShardChainPool
	ChainDb() ethdb.Database
}

Backend wraps all methods required for mining.

type E_EFuncs

type E_EFuncs func()

type Miner

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

Miner creates blocks and searches for proof-of-work values.

func New

func New(eth Backend, config *params.ChainConfig, mux *event.TypeMux, engine consensus.Engine, recommit time.Duration, gasFloor, gasCeil uint64, isLocalBlock func(block types.BlockIntf) bool) *Miner

func (*Miner) Close

func (self *Miner) Close()

func (*Miner) HashRate

func (self *Miner) HashRate() uint64

func (*Miner) Mining

func (self *Miner) Mining() bool

func (*Miner) Pending

func (self *Miner) Pending() (types.BlockIntf, *state.StateDB)

Pending returns the currently pending block and associated state.

func (*Miner) PendingBlock

func (self *Miner) PendingBlock() types.BlockIntf

PendingBlock returns the currently pending block.

Note, to access both the pending block and the pending state simultaneously, please use Pending(), as the pending state can change between multiple method calls

func (*Miner) SetEtherbase

func (self *Miner) SetEtherbase(addr common.Address)

func (*Miner) SetExtra

func (self *Miner) SetExtra(extra []byte) error

func (*Miner) SetRecommitInterval

func (self *Miner) SetRecommitInterval(interval time.Duration)

SetRecommitInterval sets the interval for sealing work resubmitting.

func (*Miner) SetupShardExps

func (self *Miner) SetupShardExps(exp uint16, enabled [32]byte)

func (*Miner) Start

func (self *Miner) Start(coinbase common.Address)

func (*Miner) Stop

func (self *Miner) Stop()
