Constructor & Destructor Documentation

◆ CDBWrapper()

CDBWrapper::CDBWrapper	(	const fs::path &	path,
		size_t	nCacheSize,
		bool	fMemory = `false`,
		bool	fWipe = `false`,
		int	nVersion = `CLIENT_VERSION`
	)

Parameters

[in]	path	Location in the filesystem where leveldb data will be stored.
[in]	nCacheSize	Configures various leveldb cache settings.
[in]	fMemory	If true, use leveldb's memory environment.
[in]	fWipe	If true, remove all existing data.
[in]	nVersion	The version used to serialize data.
