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 69 of file coins.cpp.

Here is the caller graph for this function:

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 68 of file coins.cpp.

Here is the caller graph for this function:

GetCoins()

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

virtual

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

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

Definition at line 66 of file coins.cpp.

Here is the caller graph for this function:

GetStats()

bool CCoinsView::GetStats ( CCoinsStats &  stats ) const

virtual

Calculate statistics about the unspent transaction output set.

Reimplemented in CCoinsViewBacked, and CCoinsViewDB.

Definition at line 70 of file coins.cpp.

Here is the caller graph for this function:

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 CCoinsViewCache, CCoinsViewBacked, CCoinsViewMemPool, and CCoinsViewDB.
