Member Function Documentation

BatchWrite()

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

virtual

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

Reimplemented in CCoinsViewCache, CCoinsViewBacked, and CCoinsViewDB.

Definition at line 47 of file coins.cpp.

Referenced by CCoinsViewBacked::BatchWrite(), and CCoinsViewCache::Flush().

GetBestBlock()

uint256 CCoinsView::GetBestBlock ( ) const

virtual

Retrieve the block hash whose state this CCoinsView currently represents.

Reimplemented in CCoinsViewCache, CCoinsViewBacked, and CCoinsViewDB.

Definition at line 46 of file coins.cpp.

Referenced by CCoinsViewBacked::GetBestBlock(), and CCoinsViewCache::GetBestBlock().

GetCoins()

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

virtual

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

Reimplemented in CCoinsViewMemPool, CCoinsViewCache, CCoinsViewBacked, CCoinsViewErrorCatcher, and CCoinsViewDB.

Definition at line 44 of file coins.cpp.

Referenced by CCoinsViewCache::FetchCoins(), CCoinsViewBacked::GetCoins(), CCoinsViewMemPool::GetCoins(), and CCoinsViewCache::ModifyCoins().

GetStats()

bool CCoinsView::GetStats ( CCoinsStats &  stats ) const

virtual

Calculate statistics about the unspent transaction output set.

Reimplemented in CCoinsViewBacked, and CCoinsViewDB.

Definition at line 48 of file coins.cpp.

Referenced by CCoinsViewBacked::GetStats().

HaveCoins()

bool CCoinsView::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 in CCoinsViewMemPool, CCoinsViewCache, CCoinsViewBacked, and CCoinsViewDB.

Definition at line 45 of file coins.cpp.

Referenced by CCoinsViewBacked::HaveCoins(), and CCoinsViewMemPool::HaveCoins().
