Member Function Documentation

BatchWrite()

bool CCoinsViewDB::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.

Definition at line 53 of file txdb.cpp.

GetBestBlock()

uint256 CCoinsViewDB::GetBestBlock ( ) const

virtual

Retrieve the block hash whose state this CCoinsView currently represents.

Reimplemented from CCoinsView.

Definition at line 45 of file txdb.cpp.

Here is the call graph for this function:

GetCoins()

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

virtual

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

Reimplemented from CCoinsView.

Definition at line 35 of file txdb.cpp.

Here is the call graph for this function:

GetStats()

bool CCoinsViewDB::GetStats ( CCoinsStats &  stats ) const

virtual

Calculate statistics about the unspent transaction output set.

Reimplemented from CCoinsView.

Definition at line 111 of file txdb.cpp.

HaveCoins()

bool CCoinsViewDB::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.
