Member Function Documentation

◆ checkChainLimits()

bool interfaces::anonymous_namespace{chain.cpp}::ChainImpl::checkChainLimits ( const CTransactionRef & tx )

inlineoverridevirtual

Check if transaction will pass the mempool's chain limits.

Implements interfaces::Chain.

◆ estimateMaxBlocks()

unsigned int interfaces::anonymous_namespace{chain.cpp}::ChainImpl::estimateMaxBlocks ( )

inlineoverridevirtual

Fee estimator max target.

Implements interfaces::Chain.

◆ estimateSmartFee()

CFeeRate interfaces::anonymous_namespace{chain.cpp}::ChainImpl::estimateSmartFee	(	int	num_blocks,
		bool	conservative,
		FeeCalculation *	calc
	)

inlineoverridevirtual

Estimate smart fee.

Implements interfaces::Chain.

◆ findBlock()

bool interfaces::anonymous_namespace{chain.cpp}::ChainImpl::findBlock	(	const uint256 &	hash,
		CBlock *	block,
		int64_t *	time,
		int64_t *	max_time
	)

inlineoverridevirtual

Return whether node has the block and optionally return block metadata or contents.

If a block pointer is provided to retrieve the block contents, and the block exists but doesn't have data (for example due to pruning), the block will be empty and all fields set to null.

Implements interfaces::Chain.

◆ findCoins()

void interfaces::anonymous_namespace{chain.cpp}::ChainImpl::findCoins ( std::map< COutPoint, Coin > & coins )

inlineoverridevirtual

Look up unspent output information. Returns coins in the mempool and in the current chain UTXO set. Iterates through all the keys in the map and populates the values.

Implements interfaces::Chain.

◆ getAdjustedTime()

int64_t interfaces::anonymous_namespace{chain.cpp}::ChainImpl::getAdjustedTime ( )

inlineoverridevirtual

Get adjusted time.

Implements interfaces::Chain.

◆ getTransactionAncestry()

void interfaces::anonymous_namespace{chain.cpp}::ChainImpl::getTransactionAncestry	(	const uint256 &	txid,
		size_t &	ancestors,
		size_t &	descendants
	)

inlineoverridevirtual

Calculate mempool ancestor and descendant counts for the given transaction.

Implements interfaces::Chain.

◆ guessVerificationProgress()

double interfaces::anonymous_namespace{chain.cpp}::ChainImpl::guessVerificationProgress ( const uint256 & block_hash )

inlineoverridevirtual

Estimate fraction of total transactions verified if blocks up to the specified block hash are verified.

Implements interfaces::Chain.

◆ handleNotifications()

std::unique_ptr<Handler> interfaces::anonymous_namespace{chain.cpp}::ChainImpl::handleNotifications ( Notifications & notifications )

inlineoverridevirtual

Register handler for notifications.

Implements interfaces::Chain.

◆ handleRpc()

std::unique_ptr<Handler> interfaces::anonymous_namespace{chain.cpp}::ChainImpl::handleRpc ( const CRPCCommand & command )

inlineoverridevirtual

Register handler for RPC. Command is not copied, so reference needs to remain valid until Handler is disconnected.

Implements interfaces::Chain.

◆ hasDescendantsInMempool()

bool interfaces::anonymous_namespace{chain.cpp}::ChainImpl::hasDescendantsInMempool ( const uint256 & txid )

inlineoverridevirtual

Check if transaction has descendants in mempool.

Implements interfaces::Chain.

◆ havePruned()

bool interfaces::anonymous_namespace{chain.cpp}::ChainImpl::havePruned ( )

inlineoverridevirtual

Check if any block has been pruned.

Implements interfaces::Chain.

◆ initError()

void interfaces::anonymous_namespace{chain.cpp}::ChainImpl::initError ( const std::string & message )

inlineoverridevirtual

Send init error.

Implements interfaces::Chain.

◆ initMessage()

void interfaces::anonymous_namespace{chain.cpp}::ChainImpl::initMessage ( const std::string & message )

inlineoverridevirtual

Send init message.

Implements interfaces::Chain.

◆ initWarning()

void interfaces::anonymous_namespace{chain.cpp}::ChainImpl::initWarning ( const std::string & message )

inlineoverridevirtual

Send init warning.

Implements interfaces::Chain.

◆ isInitialBlockDownload()

bool interfaces::anonymous_namespace{chain.cpp}::ChainImpl::isInitialBlockDownload ( )

inlineoverridevirtual

Check if in IBD.

Implements interfaces::Chain.

◆ isRBFOptIn()

RBFTransactionState interfaces::anonymous_namespace{chain.cpp}::ChainImpl::isRBFOptIn ( const CTransaction & tx )

inlineoverridevirtual

Check if transaction is RBF opt in.

Implements interfaces::Chain.

◆ isReadyToBroadcast()

bool interfaces::anonymous_namespace{chain.cpp}::ChainImpl::isReadyToBroadcast ( )

inlineoverridevirtual

Check if the node is ready to broadcast transactions.

Implements interfaces::Chain.

◆ loadWallet()

void interfaces::anonymous_namespace{chain.cpp}::ChainImpl::loadWallet ( std::unique_ptr< Wallet > wallet )

inlineoverridevirtual

Send wallet load notification to the GUI.

Implements interfaces::Chain.

◆ lock()

std::unique_ptr<Chain::Lock> interfaces::anonymous_namespace{chain.cpp}::ChainImpl::lock ( bool try_lock )

inlineoverridevirtual

Return Lock interface. Chain is locked when this is called, and unlocked when the returned interface is freed.

Implements interfaces::Chain.

◆ mempoolMinFee()

CFeeRate interfaces::anonymous_namespace{chain.cpp}::ChainImpl::mempoolMinFee ( )

inlineoverridevirtual

Mempool minimum fee.

Implements interfaces::Chain.

◆ p2pEnabled()

bool interfaces::anonymous_namespace{chain.cpp}::ChainImpl::p2pEnabled ( )

inlineoverridevirtual

Check if p2p enabled.

Implements interfaces::Chain.

◆ relayDustFee()

CFeeRate interfaces::anonymous_namespace{chain.cpp}::ChainImpl::relayDustFee ( )

inlineoverridevirtual

Relay dust fee setting (-dustrelayfee), reflecting lowest rate it's economical to spend.

Implements interfaces::Chain.

◆ relayIncrementalFee()

CFeeRate interfaces::anonymous_namespace{chain.cpp}::ChainImpl::relayIncrementalFee ( )

inlineoverridevirtual

Relay incremental fee setting (-incrementalrelayfee), reflecting cost of relay.

Implements interfaces::Chain.

◆ relayMinFee()

CFeeRate interfaces::anonymous_namespace{chain.cpp}::ChainImpl::relayMinFee ( )

inlineoverridevirtual

Relay current minimum fee (from -minrelaytxfee and -incrementalrelayfee settings).

Implements interfaces::Chain.

◆ relayTransaction()

void interfaces::anonymous_namespace{chain.cpp}::ChainImpl::relayTransaction ( const uint256 & txid )

inlineoverridevirtual

Relay transaction.

Implements interfaces::Chain.

◆ requestMempoolTransactions()

void interfaces::anonymous_namespace{chain.cpp}::ChainImpl::requestMempoolTransactions ( Notifications & notifications )

inlineoverridevirtual

Synchronously send TransactionAddedToMempool notifications about all current mempool transactions to the specified handler and return after the last one is sent. These notifications aren't coordinated with async notifications sent by handleNotifications, so out of date async notifications from handleNotifications can arrive during and after synchronous notifications from requestMempoolTransactions. Clients need to be prepared to handle this by ignoring notifications about unknown removed transactions and already added new transactions.

Implements interfaces::Chain.

inlineoverridevirtual

Check if deprecated RPC is enabled.

Implements interfaces::Chain.

		std::function< void()>	fn,
		int64_t	seconds
	)

inlineoverridevirtual

Run function after given number of seconds. Cancel any previous calls with same name.

Implements interfaces::Chain.

◆ rpcSerializationFlags()

int interfaces::anonymous_namespace{chain.cpp}::ChainImpl::rpcSerializationFlags ( )

inlineoverridevirtual

Current RPC serialization flags.

Implements interfaces::Chain.

◆ showProgress()

void interfaces::anonymous_namespace{chain.cpp}::ChainImpl::showProgress	(	const std::string &	title,
		int	progress,
		bool	resume_possible
	)

inlineoverridevirtual

Send progress indicator.

Implements interfaces::Chain.

◆ shutdownRequested()

bool interfaces::anonymous_namespace{chain.cpp}::ChainImpl::shutdownRequested ( )

inlineoverridevirtual

Check if shutdown requested.

Implements interfaces::Chain.

◆ waitForNotificationsIfNewBlocksConnected()

void interfaces::anonymous_namespace{chain.cpp}::ChainImpl::waitForNotificationsIfNewBlocksConnected ( const uint256 & old_tip )

inlineoverridevirtual

Wait for pending notifications to be processed unless block hash points to the current chain tip, or to a possible descendant of the current chain tip that isn't currently connected.

Implements interfaces::Chain.
