Member Typedef Documentation

KeyValPair

typedef std::pair<std::vector<unsigned char>, std::vector<unsigned char> > CDBEnv::KeyValPair

Salvage data from a file that Verify says is bad. fAggressive sets the DB_AGGRESSIVE flag (see berkeley DB->verify() method documentation). Appends binary key/value pairs to vResult, returns true if successful. NOTE: reads the entire database into memory, so cannot be used for huge databases.

Member Enumeration Documentation

VerifyResult

enum CDBEnv::VerifyResult

Verify that database file strFile is OK. If it is not, call the callback to try to recover. This must be called BEFORE strFile is opened. Returns true if strFile is OK.
