Type Members

1. case class Blockchain(headers: Vector[BlockHeaderDb]) extends BaseBlockChain with Product with Serializable

   

   <invalid inheritdoc annotation>

2. sealed abstract class BlockchainUpdate extends AnyRef

   

   Represens the state of a batch of BlockHeaders being added to our blockchain

   Represens the state of a batch of BlockHeaders being added to our blockchain

   An example of a Failed update is when we receive a BlockHeader that is invalid and because of a TipUpdateFailure because of BadPOW or a BadNonce etc

3. sealed abstract class ChainException extends RuntimeException

   

   A base class for various types of block chain exceptions

4. case class ChainHandler(blockHeaderDAO: BlockHeaderDAO, filterHeaderDAO: CompactFilterHeaderDAO, filterDAO: CompactFilterDAO, blockchains: Vector[Blockchain], blockFilterCheckpoints: Map[DoubleSha256DigestBE, DoubleSha256DigestBE])(implicit chainConfig: ChainAppConfig, executionContext: ExecutionContext) extends ChainApi with ChainVerificationLogger with Product with Serializable

   

   Chain Handler is meant to be the reference implementation of ChainApi, this is the entry point in to the chain project.

   blockHeaderDAO

   block header DB

   filterHeaderDAO

   filter header DB

   filterDAO

   filter DB

   blockchains

   current blockchains

   blockFilterCheckpoints

   compact filter checkpoints for filter header verification in form of a map (block header hash -> filter header hash)

   chainConfig

   config file

5. case class CheckHeaderResult(result: TipUpdateResult, chain: Blockchain) extends Product with Serializable

   

6. sealed trait ConnectTipResult extends AnyRef

   

   The result indicating how the TipUpdateResult modified the chain.

   The result indicating how the TipUpdateResult modified the chain.

   We can

   1. Extend the chain 2. Reorg the chain 3. Fail to connect to anything in the chain

7. case class DuplicateFilters(message: String) extends ChainException with Product with Serializable

   

   org.bitcoins.chain.blockchain.ChainHandler tried to process multiple filters for the same block hash

8. case class InvalidBlockRange(message: String) extends ChainException with Product with Serializable

   

   The given block range is invalid

9. case class UnknownBlockHash(message: String) extends ChainException with Product with Serializable

   

   org.bitcoins.chain.blockchain.ChainHandler cannot find a blockchain item by its block hash

10. case class UnknownBlockHeight(message: String) extends ChainException with Product with Serializable

    

    org.bitcoins.chain.blockchain.ChainHandler cannot find a blockchain item by its height

11. case class UnknownFilterHash(message: String) extends ChainException with Product with Serializable

    

    org.bitcoins.chain.blockchain.ChainHandler cannot find a compact filter or header by its filter hash
