Member Function Documentation

AddToBlock()

void node::BlockAssembler::AddToBlock ( const CTxMemPoolEntryRef &  entry )

private

Add a tx to the block.

Definition at line 210 of file miner.cpp.

Here is the call graph for this function:

Here is the caller graph for this function:

addTxs()

void node::BlockAssembler::addTxs ( const CTxMemPool &  mempool )

private

Add transactions from the mempool based on individual tx feerate.

addTxs includes transactions paying a fee by ensuring that the partial ordering of transactions is maintained.

That is to say children come after parents, despite having a potentially larger fee.

Here is the caller graph for this function:

CheckTx()

bool node::BlockAssembler::CheckTx ( const CTransaction &  tx ) const

private

Check the transaction for finality, etc before adding to block.

Definition at line 225 of file miner.cpp.

Here is the caller graph for this function:

CreateNewBlock()

std::unique_ptr< CBlockTemplate > node::BlockAssembler::CreateNewBlock

(

const CScript &

scriptPubKeyIn

)

Construct a new block template with coinbase to scriptPubKeyIn.

Definition at line 74 of file miner.cpp.

Here is the call graph for this function:

GetMaxGeneratedBlockSize()

uint64_t node::BlockAssembler::GetMaxGeneratedBlockSize ( ) const

inline

Definition at line 84 of file miner.h.

Here is the call graph for this function:

resetBlock()

void node::BlockAssembler::resetBlock ( )

private

Clear the block's state and prepare for assembling a new block.
