type ArgsNewRewardsCreator struct {
	ShardCoordinator sharding.Coordinator
	AddrConverter    state.AddressConverter
	RewardsStorage   storage.Storer
	MiniBlockStorage storage.Storer
	Hasher           hashing.Hasher

}

ArgsPendingMiniBlocks is a structure that contains 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) GetSavedStateKey 

func (t TestTrigger) GetSavedStateKey() []byte

GetSavedStateKey returns the last saved trigger state key

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) LoadState 

func (t TestTrigger) LoadState(key []byte) error

LoadState loads into trigger the saved state

func (TestTrigger) ReceivedHeader added in v1.0.67 

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

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

func (TestTrigger) RequestEpochStartIfNeeded 

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

RequestEpochStartIfNeeded request the needed epoch start block if metablock with new epoch was received

func (TestTrigger) Revert added in v1.0.67 

func (t TestTrigger) Revert(round uint64)

Revert sets the start of epoch back to true

func (TestTrigger) SetCurrentEpochStartRound 

func (t TestTrigger) SetCurrentEpochStartRound(round uint64)
