Member Function Documentation

appendExtraStats()

virtual void mongo::DatabaseCatalogEntry::appendExtraStats ( OperationContext *  opCtx, BSONObjBuilder *  out, double  scale  ) const

pure virtual

Implemented in mongo::MMAPV1DatabaseCatalogEntry, and mongo::KVDatabaseCatalogEntryBase.

createCollection()

virtual Status mongo::DatabaseCatalogEntry::createCollection ( OperationContext *  opCtx, StringData  ns, const CollectionOptions &  options, bool  allocateDefaultSpace  )

pure virtual

Implemented in mongo::MMAPV1DatabaseCatalogEntry, and mongo::KVDatabaseCatalogEntryBase.

currentFilesCompatible()

virtual Status mongo::DatabaseCatalogEntry::currentFilesCompatible ( OperationContext *  opCtx ) const

pure virtual

Returns whethers the data files are compatible with the current code:

• Status::OK() if the data files are compatible with the current code.
• ErrorCodes::CanRepairToDowngrade if the data files are incompatible with the current code, but a –repair would make them compatible. For example, when rebuilding all indexes in the data files would resolve the incompatibility.
• ErrorCodes::MustUpgrade if the data files are incompatible with the current code and a newer version is required to start up.

Implemented in mongo::MMAPV1DatabaseCatalogEntry, and mongo::KVDatabaseCatalogEntryBase.
