Added CreatePollTransactionData constructor that doesn't need signature (for creating new transactions).
Added missing "published" timestamp support to PollData and Poll.
Removed extraneous timestamp test from Block.isValid.
Corrected inconsistent column names in poll-related tables in HSQLDBDatabaseUpdates.
HSQLDBRepository.checkedExecute(PreparedStatement) now takes extra Object... params
so that values can be bound to placeholders. Code moved from checkedExecute(String, Object...).
This fixes an issue with exists(String, String, Object...) where placeholders weren't having
any values bound to them. (Also removed "ORDER BY NULL" clause which isn't supported by HSQLDB).
HSQLDBVotingRepository method stubs fleshed out with real code.
TransactionTests rejigged but more work needed to test various transactions before/after their feature
release. e.g. testing create poll transactions before & after they supposedly went live.
Could do with a GenesisBlock constructor that takes a timestamp for testing purposes?
CreatePollTransactionTransformer now skips serializing a null signature,
in the same way PaymentTransactionTransformer does, to aid getBytesLessSignature().
This will probably need to be rolled out to all other transaction types.
* Add implementation for Account.getBalance(assetId, numberOfConfirmations)
* Added orphan() code to Block (CIYAM AT not yet supported)
* Added getOrder() 'navigation' method to CreateOrderTransaction
* Added missing transaction-type cases to various switches in Transaction, transformers, repositories, etc.
* Various repository delete() methods added
* Added save/delete support for transaction types that include payments, like multipayment and arbitrary
* Changed "recipient" in HSQLDB SharedTransactionPayments from QoraPublicKey to QoraAddress
* Code added for calculating an account's generating balance. (CIYAM AT support yet to be added).
* Added associated code in Block for calculating next block's timestamp, generating balance, base target, etc.
* ValidationResult enum added to Block, mostly to aid debugging.
* Block.isValid() now returns ValidationResult instead of boolean.
* Block.isValid() now has added proof-of-stake tests.
* Some blockchain-related constants, like feature release heights/timestamps, moved from Block to BlockChain.
* Added better Block constructor for use when creating a new block.
* Added helpful 'navigation' methods to Block to get to block's parent (or child).
* Changed visibility of block's individual signature calculators to protected, in favour of public sign() method.
* Added asset existence check to Payment.isValid.
* All current transaction objects (qora.transaction.*) now have private subclassed transaction variable to save multiple casts in various methods.
* Also added to above:
* isInvolved(Account) : boolean
* getRecipients() : List<Account>
* getAmount(Account) : BigDecimal
* Added BlockRepository.getLastBlock() to fetch highest block in blockchain.
* Added diagnostics to HSQLDBRepository.close() to alert if there are any uncommitted changes during closure.
(Currently under suspicion due to possible HSQLDB bug!)
* Old "TransactionTests" renamed to "SerializationTests" as that's what they really are.
* New "TransactionTests" added to test processing of transactions. (Currently only a PaymentTransaction).
* PaymentTransformer.toBytes() detects and skips null signature. This was causing issues with Transaction.toBytesLessSignature().
Needs rolling out to other transaction types if acceptable.
