Types

type ArgCreatePathManager

type ArgCreatePathManager struct {
	WorkingDir string
	ChainID    string
}

ArgCreatePathManager is used to pass the strings to the path manager factory function

type ArgsNewOpenStorageUnits

type ArgsNewOpenStorageUnits struct {
	BootstrapDataProvider     BootstrapDataProviderHandler
	LatestStorageDataProvider storage.LatestStorageDataProviderHandler
	DefaultEpochString        string
	DefaultShardString        string
}

ArgsNewOpenStorageUnits defines the arguments in order to open a set of storage units from disk

type BootstrapDataProviderHandler

type BootstrapDataProviderHandler interface {
	LoadForPath(persisterFactory storage.PersisterFactory, path string) (*bootstrapStorage.BootstrapData, storage.Storer, error)
	GetStorer(storer storage.Storer) (process.BootStorer, error)
	IsInterfaceNil() bool
}

BootstrapDataProviderHandler defines which actions should be done for loading bootstrap data from the boot storer

type NodeTypeProviderHandler

type NodeTypeProviderHandler interface {
	SetType(nodeType core.NodeType)
	GetType() core.NodeType
	IsInterfaceNil() bool
}

NodeTypeProviderHandler defines the actions needed for a component that can handle the node type

type PersisterFactory

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

PersisterFactory is the factory which will handle creating new databases

func NewPersisterFactory

func NewPersisterFactory(config config.DBConfig) *PersisterFactory

NewPersisterFactory will return a new instance of a PersisterFactory

func (*PersisterFactory) Create

func (pf *PersisterFactory) Create(path string) (storage.Persister, error)

Create will return a new instance of a DB with a given path

func (*PersisterFactory) CreateDisabled

func (pf *PersisterFactory) CreateDisabled() storage.Persister

CreateDisabled will return a new disabled persister

func (*PersisterFactory) IsInterfaceNil

func (pf *PersisterFactory) IsInterfaceNil() bool

IsInterfaceNil returns true if there is no value under the interface

type StorageServiceFactory

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

StorageServiceFactory handles the creation of storage services for both meta and shards

func NewStorageServiceFactory

func NewStorageServiceFactory(args StorageServiceFactoryArgs) (*StorageServiceFactory, error)

NewStorageServiceFactory will return a new instance of StorageServiceFactory

func (*StorageServiceFactory) CreateForMeta

func (psf *StorageServiceFactory) CreateForMeta() (dataRetriever.StorageService, error)

CreateForMeta will return the storage service which contains all storers needed for metachain

func (*StorageServiceFactory) CreateForShard

func (psf *StorageServiceFactory) CreateForShard() (dataRetriever.StorageService, error)

CreateForShard will return the storage service which contains all storers needed for a shard

type StorageServiceFactoryArgs

type StorageServiceFactoryArgs struct {
	Config                        config.Config
	PrefsConfig                   config.PreferencesConfig
	ShardCoordinator              storage.ShardCoordinator
	PathManager                   storage.PathManagerHandler
	EpochStartNotifier            epochStart.EpochStartNotifier
	NodeTypeProvider              NodeTypeProviderHandler
	StorageType                   StorageServiceType
	CurrentEpoch                  uint32
	CreateTrieEpochRootHashStorer bool
}

StorageServiceFactoryArgs holds the arguments needed for creating a new storage service factory

type StorageServiceType

type StorageServiceType string

StorageServiceType defines the type of StorageService

const (
	// BootstrapStorageService is used when the node is bootstrapping
	BootstrapStorageService StorageServiceType = "bootstrap"

	// ProcessStorageService is used in normal processing
	ProcessStorageService StorageServiceType = "process"
)
