Detailed Description
CCoinsView that brings transactions from a mempool into view. It does not check for spendings by memory pool transactions. Instead, it provides access to all Coins which are either unspent in the base CCoinsView, or are outputs from any mempool transaction! This allows transaction replacement to work as expected, as you want to have all inputs "available" to check signatures, and any cycles in the dependency graph are checked directly in AcceptToMemoryPool. It also allows you to sign a double-spend directly in signrawtransactionwithkey and signrawtransactionwithwallet, as long as the conflicting transaction is not yet confirmed.

Member Function Documentation
◆ GetCoin()
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.
