Member Function Documentation

◆ BatchWrite()

bool CCoinsViewBacked::BatchWrite ( CCoinsMap &  mapCoins,
const uint256 &  hashBlock 
)
virtual

Do a bulk modification (multiple CCoins changes + BestBlock change). The passed mapCoins can be modified.

Reimplemented from CCoinsView.

Reimplemented in CCoinsViewCache.

Definition at line 56 of file coins.cpp.

◆ GetBestBlock()

uint256 CCoinsViewBacked::GetBestBlock ( ) const
virtual

Retrieve the block hash whose state this CCoinsView currently represents.

Reimplemented from CCoinsView.

Reimplemented in CCoinsViewCache.

Definition at line 54 of file coins.cpp.

◆ GetCoins()

bool CCoinsViewBacked::GetCoins ( const uint256 &  txid,
CCoins &  coins 
) const
virtual

Retrieve the CCoins (unspent transaction outputs) for a given txid.

Reimplemented from CCoinsView.

Reimplemented in CCoinsViewMemPool, CCoinsViewCache, and CCoinsViewErrorCatcher.

Definition at line 52 of file coins.cpp.

Referenced by CCoinsViewErrorCatcher::GetCoins().

◆ GetStats()

bool CCoinsViewBacked::GetStats ( CCoinsStats &  stats) const
virtual

Calculate statistics about the unspent transaction output set.

Reimplemented from CCoinsView.

Definition at line 57 of file coins.cpp.

Referenced by gettxoutsetinfo().

◆ HaveCoins()

bool CCoinsViewBacked::HaveCoins ( const uint256 &  txid) const
virtual

Just check whether we have data for a given txid. This may (but cannot always) return true for fully spent transactions

Reimplemented from CCoinsView.

Reimplemented in CCoinsViewMemPool, and CCoinsViewCache.

Definition at line 53 of file coins.cpp.

◆ SetBackend()

void CCoinsViewBacked::SetBackend ( CCoinsView &  viewIn)

Definition at line 55 of file coins.cpp.
