Classes in com.google.bitcoin.core used by com.google.bitcoin.core

AbstractBlockChain
An AbstractBlockChain holds a series of Block objects, links them together, and knows how to verify that the chain follows the rules of the NetworkParameters for this chain.

AbstractBlockChain.NewBlockType

AbstractPeerEventListener
Convenience implementation of PeerEventListener.

Block
A block is a group of transactions, and is one of the fundamental data structures of the Bitcoin system.

BlockChainListener
Implementors can be connected to a BlockChain and have its methods called when various things happen that modify the state of the chain, for example: new blocks being received, a re-org occurring, or the best chain head changing.

BloomFilter
A Bloom filter is a probabilistic data structure which can be sent to another client so that it can avoid sending us transactions that aren't relevant to our set of keys.

BloomFilter.BloomUpdate
The BLOOM_UPDATE_* constants control when the bloom filter is auto-updated by the peer using it as a filter, either never, for all outputs or only for pay-2-pubkey outputs (default)

ChildMessage
Represents a Message type that can be contained within another Message.

DumpedPrivateKey
Parses and generates private keys in the form used by the Bitcoin "dumpprivkey" command.

ECKey
Represents an elliptic curve public and (optionally) private key, usable for digital signatures but not encryption.

EmptyMessage
Parent class for header only messages that don't have a payload.

FilteredBlock
A FilteredBlock is used to relay a block with its transactions filtered using a BloomFilter.

TransactionConfidence.Source
Information about where the transaction was first seen (network, sent direct from peer, created by ourselves).

TransactionInput
A transfer of coins from one address to another creates a transaction in which the outputs can be claimed by the recipient in the input of another transaction.

TransactionInput.ConnectionResult

TransactionInput.ConnectMode

TransactionOutPoint
This message is a reference or pointer to an output of a different transaction.

VerificationException

VersionedChecksummedBytes

VersionMessage
A VersionMessage holds information exchanged during connection setup with another peer.

Wallet
A Wallet stores keys and a record of transactions that send and receive value from those keys.

Wallet.BalanceType
It's possible to calculate a wallets balance from multiple points of view.

Wallet.SendRequest
A SendRequest gives the wallet information about precisely how to send money to a recipient or set of recipients.

Wallet.SendResult
A SendResult is returned to you as part of sending coins to a recipient.

WalletEventListener
Implementors are called when the contents of the wallet changes, for instance due to receiving/sending money or a block chain re-organize.

WalletExtension
An object implementing this interface can be added to a Wallet and provide arbitrary byte arrays that will be serialized alongside the wallet.

WrongNetworkException
This exception is thrown by the Address class when you try and decode an address with a version code that isn't used by that network.
