type InstancesManager

type InstancesManager struct {
}

InstancesManager manager of evm instances

func (*InstancesManager) AfterSchedule

func (*InstancesManager) AfterSchedule(blockFingerprint string, blockHeight uint64)

AfterSchedule do sth. after schedule a block

func (*InstancesManager) BeforeSchedule

func (*InstancesManager) BeforeSchedule(blockFingerprint string, blockHeight uint64)

BeforeSchedule do sth. before schedule a block

func (*InstancesManager) NewRuntimeInstance

func (*InstancesManager) NewRuntimeInstance(txSimContext protocol.TxSimContext, chainId, method string, codePath string,
	contract *commonPb.Contract, byteCode []byte, log protocol.Logger) (protocol.RuntimeInstance, error)

NewRuntimeInstance new an evm instance

func (*InstancesManager) StartVM

func (*InstancesManager) StartVM() error

StartVM start vm

func (*InstancesManager) StopVM

func (*InstancesManager) StopVM() error

StopVM stop vm

type RuntimeInstance

type RuntimeInstance struct {
	Method  string // invoke contract method
	ChainId string // chain id
	//Address       *evmutils.Int      //address
	Contract      *commonPb.Contract // contract info
	Log           protocol.Logger
	TxSimContext  protocol.TxSimContext
	ContractEvent []*commonPb.ContractEvent
}

RuntimeInstance evm runtime

func (*RuntimeInstance) Invoke

func (r *RuntimeInstance) Invoke(contract *commonPb.Contract, method string, byteCode []byte,
	parameters map[string][]byte, txSimContext protocol.TxSimContext, gasUsed uint64) (
	contractResult *commonPb.ContractResult, specialTxType protocol.ExecOrderTxType)

Invoke contract by call vm, implement protocol.RuntimeInstance
