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.

GetBestBlock()

uint256 CCoinsViewBacked::GetBestBlock ( ) const

virtual

Retrieve the block hash whose state this CCoinsView currently represents.

GetStats()

bool CCoinsViewBacked::GetStats ( CCoinsStats &  stats ) const

virtual

Calculate statistics about the unspent transaction output set.
