CCoinsViewErrorCatcher Class Reference

This is a minimally invasive approach to shutdown on LevelDB read errors from the chainstate, while keeping user interface out of the common library, which is shared between fabcoind, and fabcoin-qt and non-server tools. More...

bool CCoinsViewErrorCatcher::GetCoin ( const COutPoint &  outpoint, Coin &  coin  ) const

inlineoverridevirtual

Retrieve the Coin (unspent transaction output) for a given outpoint.

Returns true only when an unspent coin was found, which is returned in coin. When false is returned, coin's value is unspecified.

Reimplemented from CCoinsViewBacked.
