Functions

func NewEpochStartTrigger

func NewEpochStartTrigger(args *ArgsNewMetaEpochStartTrigger) (*trigger, error)

NewEpochStartTrigger creates a trigger for start of epoch

func NewPendingMiniBlocks

func NewPendingMiniBlocks(args *ArgsPendingMiniBlocks) (*pendingMiniBlockHeaders, error)

NewPendingMiniBlocks will create a new pendingMiniBlockHeaders object

Types

type ArgsNewMetaEpochStartTrigger

type ArgsNewMetaEpochStartTrigger struct {
	GenesisTime        time.Time
	Settings           *config.EpochStartConfig
	Epoch              uint32
	EpochStartRound    uint64
	EpochStartNotifier epochStart.StartOfEpochNotifier
	Marshalizer        marshal.Marshalizer
	Storage            dataRetriever.StorageService
}

ArgsNewMetaEpochStartTrigger defines struct needed to create a new start of epoch trigger

type ArgsPendingMiniBlocks

type ArgsPendingMiniBlocks struct {
	Marshalizer      marshal.Marshalizer
	Storage          storage.Storer
	MetaBlockStorage storage.Storer
	MetaBlockPool    storage.Cacher
}

ArgsPendingMiniBlocks is structure that contain components that are used to create a new pendingMiniBlockHeaders object

type TestTrigger

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

TestTrigger extends start of epoch trigger and is used in integration tests as it exposes some functions that are not supposed to be used in production code Exported functions simplify the reproduction of edge cases

func (TestTrigger) Epoch

func (t TestTrigger) Epoch() uint32

Epoch return the current epoch

func (TestTrigger) EpochFinalityAttestingRound

func (t TestTrigger) EpochFinalityAttestingRound() uint64

EpochFinalityAttestingRound returns the round when epoch start block was finalized

func (TestTrigger) EpochStartMetaHdrHash

func (t TestTrigger) EpochStartMetaHdrHash() []byte

EpochStartMetaHdrHash returns the announcing meta header hash which created the new epoch

func (TestTrigger) EpochStartRound

func (t TestTrigger) EpochStartRound() uint64

EpochStartRound returns the start round of the current epoch

func (TestTrigger) ForceEpochStart

func (t TestTrigger) ForceEpochStart(round uint64) error

ForceEpochStart sets the conditions for start of epoch to true in case of edge cases

func (*TestTrigger) GetRoundsPerEpoch

func (t *TestTrigger) GetRoundsPerEpoch() uint64

GetRoundsPerEpoch gets the number of rounds per epoch

func (TestTrigger) IsEpochStart

func (t TestTrigger) IsEpochStart() bool

IsEpochStart return true if conditions are fulfilled for start of epoch

func (TestTrigger) IsInterfaceNil

func (t TestTrigger) IsInterfaceNil() bool

IsInterfaceNil return true if underlying object is nil

func (TestTrigger) ReceivedHeader

func (t TestTrigger) ReceivedHeader(_ data.HeaderHandler)

ReceivedHeader saved the header into pool to verify if end-of-epoch conditions are fulfilled

func (TestTrigger) Revert

func (t TestTrigger) Revert()

Revert sets the start of epoch back to true

func (TestTrigger) SetCurrentEpochStartRound

func (t TestTrigger) SetCurrentEpochStartRound(round uint64)

SetLastEpochStartRound sets the round when the current epoch started

func (TestTrigger) SetEpochStartMetaHdrHash

func (t TestTrigger) SetEpochStartMetaHdrHash(metaHdrHash []byte)

SetEpochStartMetaHdrHash sets the epoch start meta header hase

func (TestTrigger) SetFinalityAttestingRound

func (t TestTrigger) SetFinalityAttestingRound(round uint64)

SetFinalityAttestingRound sets the round which finalized the start of epoch block

func (TestTrigger) SetProcessed

func (t TestTrigger) SetProcessed(header data.HeaderHandler)

SetProcessed sets start of epoch to false and cleans underlying structure

func (*TestTrigger) SetRoundsPerEpoch

func (t *TestTrigger) SetRoundsPerEpoch(roundsPerEpoch uint64)

SetRoundsPerEpoch sets the number of round between epochs

func (*TestTrigger) SetTrigger

func (t *TestTrigger) SetTrigger(triggerHandler epochStart.TriggerHandler)

SetTrigger sets the start of epoch trigger

func (TestTrigger) Update

func (t TestTrigger) Update(round uint64)

Update processes changes in the trigger
