Interface Summary

Interface	Description
CoinSelector	A CoinSelector is responsible for picking some outputs to spend, from the list of all possible outputs.
EncryptableKeyChain	An encryptable key chain is a key-chain that can be encrypted with a user-provided password or AES key.
KeyBag	A KeyBag is simply an object that can map public keys, their 160-bit hashes and script hashes to ECKey and RedeemData objects.
KeyChain	A KeyChain is a class that stores a collection of keys for a Wallet.
KeyChainFactory	Factory interface for creation keychains while de-serializing a wallet.

RiskAnalysis	A RiskAnalysis represents an analysis of how likely it is that a transaction (and its dependencies) represents a possible double spending attack.
RiskAnalysis.Analyzer
WalletExtension	An object implementing this interface can be added to a Wallet and provide arbitrary byte arrays that will be serialized alongside the wallet.
WalletFiles.Listener	Implementors can do pre/post treatment of the wallet file.
WalletProtobufSerializer.WalletFactory

Class Summary

Class	Description
AllowUnconfirmedCoinSelector	This coin selector will select any transaction at all, regardless of where it came from or whether it was confirmed yet.
BasicKeyChain	A KeyChain that implements the simplest model possible: it can have keys imported into it, and just acts as a dumb bag of keys.
CoinSelection	Represents the results of a CoinSelector.select(Coin, java.util.List) operation.
DecryptingKeyBag	A DecryptingKeyBag filters a pre-existing key bag, decrypting keys as they are requested using the provided AES key.
DefaultCoinSelector	This class implements a CoinSelector which attempts to get the highest priority possible.
DefaultKeyChainFactory	Default factory for creating keychains while de-serializing.
DefaultRiskAnalysis	The default risk analysis.
DefaultRiskAnalysis.Analyzer
DeterministicKeyChain	A deterministic key chain is a KeyChain that uses the BIP 32 standard, as implemented by DeterministicHierarchy, to derive all the keys in the keychain from a master seed.
DeterministicKeyChain.Builder<T extends DeterministicKeyChain.Builder<T>>
DeterministicSeed	Holds the seed bytes for the BIP32 deterministic wallet algorithm, inside a DeterministicKeyChain.
FilteringCoinSelector	A filtering coin selector delegates to another coin selector, but won't select outputs spent by the given transactions.
KeyChainGroup	A KeyChainGroup is used by the Wallet and manages: a BasicKeyChain object (which will normally be empty), and zero or more DeterministicKeyChains.
KeyTimeCoinSelector	A coin selector that takes all coins assigned to keys created before the given timestamp.
MarriedKeyChain	A multi-signature keychain using synchronized HD keys (a.k.a HDM)
MarriedKeyChain.Builder<T extends MarriedKeyChain.Builder<T>>	Builds a MarriedKeyChain

RedeemData	This class aggregates data required to spend transaction output.
SendRequest	A SendRequest gives the wallet information about precisely how to send money to a recipient or set of recipients.
Wallet	A Wallet stores keys and a record of transactions that send and receive value from those keys.
Wallet.SendResult	A SendResult is returned to you as part of sending coins to a recipient.
WalletFiles	A class that handles atomic and optionally delayed writing of the wallet file to disk.
WalletProtobufSerializer	Serialize and de-serialize a wallet to a byte stream containing a protocol buffer.
WalletTransaction	Stores data about a transaction that is only relevant to the Wallet class.

Enum Summary

Enum	Description
BasicKeyChain.State	Whether this basic key chain is empty, full of regular (usable for signing) keys, or full of watching keys.

Exception Summary

Exception	Description
AllRandomKeysRotating	Indicates that an attempt was made to upgrade a random wallet to deterministic, but there were no non-rotating random keys to use as source material for the seed.
DeterministicUpgradeRequiredException	Indicates that an attempt was made to use HD wallet features on a wallet that was deserialized from an old, pre-HD random wallet without calling upgradeToDeterministic() beforehand.
DeterministicUpgradeRequiresPassword	Indicates that the pre-HD random wallet is encrypted, so you should try the upgrade again after getting the users password.
UnreadableWalletException	Thrown by the WalletProtobufSerializer when the serialized protocol buffer is either corrupted, internally inconsistent or appears to be from the future.
UnreadableWalletException.BadPassword
UnreadableWalletException.FutureVersion
UnreadableWalletException.WrongNetwork
Wallet.CompletionException	Class of exceptions thrown in Wallet.completeTx(SendRequest).
Wallet.CouldNotAdjustDownwards	Thrown when we were trying to empty the wallet, and the total amount of money we were trying to empty after being reduced for the fee was smaller than the min payment.
Wallet.DustySendRequested	Thrown if the resultant transaction would violate the dust rules (an output that's too small to be worthwhile).
Wallet.ExceededMaxTransactionSize	Thrown if the resultant transaction is too big for Bitcoin to process.
Wallet.MultipleOpReturnRequested	Thrown if there is more than one OP_RETURN output for the resultant transaction.
