Types ¶
type Collection ¶
type Collection interface {
// ShardChain returns the blockchain for the given shard,
// opening one as necessary.
ShardChain(shardID uint32) (*core.BlockChain, error)
// CloseShardChain closes the given shard chain.
CloseShardChain(shardID uint32) error
// Close closes all shard chains.
Close() error
}
Collection is a collection of per-shard blockchains.
type CollectionImpl ¶
type CollectionImpl struct {
// contains filtered or unexported fields
}
CollectionImpl is the main implementation of the shard chain collection. See the Collection interface for details.
func NewCollection ¶
func NewCollection( dbFactory DBFactory, dbInit DBInitializer, engine engine.Engine, chainConfig *params.ChainConfig, ) *CollectionImpl
NewCollection creates and returns a new shard chain collection.
dbFactory is the shard chain database factory to use.
dbInit is the shard chain initializer to use when the database returned by the factory is brand new (empty).
func (*CollectionImpl) Close ¶
func (sc *CollectionImpl) Close() error
Close closes all shard chains.
func (*CollectionImpl) CloseShardChain ¶
func (sc *CollectionImpl) CloseShardChain(shardID uint32) error
CloseShardChain closes the given shard chain.
func (*CollectionImpl) DisableCache ¶
func (sc *CollectionImpl) DisableCache(shardID uint32)
DisableCache disables caching mode for newly opened chains. It does not affect already open chains. For best effect, use this immediately after creating collection.
func (*CollectionImpl) ShardChain ¶
func (sc *CollectionImpl) ShardChain(shardID uint32) (*core.BlockChain, error)
ShardChain returns the blockchain for the given shard, opening one as necessary.
type DBFactory ¶
type DBFactory interface {
// NewChainDB returns a new database for the blockchain for
// given shard.
NewChainDB(shardID uint32) (ethdb.Database, error)
}
DBFactory is a blockchain database factory.
type DBInitializer ¶
DBInitializer initializes a newly created chain database.
type LDBFactory ¶
type LDBFactory struct {
RootDir string // directory in which to put shard databases in.
}
LDBFactory is a LDB-backed blockchain database factory.
func (*LDBFactory) NewChainDB ¶
func (f *LDBFactory) NewChainDB(shardID uint32) (ethdb.Database, error)
NewChainDB returns a new LDB for the blockchain for given shard.
type MemDBFactory ¶
type MemDBFactory struct{}
MemDBFactory is a memory-backed blockchain database factory.
func (*MemDBFactory) NewChainDB ¶
func (f *MemDBFactory) NewChainDB(shardID uint32) (ethdb.Database, error)
NewChainDB returns a new memDB for the blockchain for given shard.
