Member Function Documentation

◆ getCursor()

std::unique_ptr< SeekableRecordCursor > mongo::PrefixedWiredTigerRecordStore::getCursor	(	OperationContext *	opCtx,
		bool	forward
	)		const

overridevirtual

Returns a new cursor over this record store.

The cursor is logically positioned before the first (or last if !forward) Record in the collection so that Record will be returned on the first call to next(). Implementations are allowed to lazily seek to the first Record when next() is called rather than doing it on construction.

Implements mongo::WiredTigerRecordStore.

◆ getKey()

RecordId mongo::PrefixedWiredTigerRecordStore::getKey ( WT_CURSOR * cursor ) const

protectedvirtual

Implements mongo::WiredTigerRecordStore.

◆ getRandomCursorWithOptions()

std::unique_ptr< RecordCursor > mongo::PrefixedWiredTigerRecordStore::getRandomCursorWithOptions	(	OperationContext *	opCtx,
		StringData	extraConfig

Implements mongo::WiredTigerRecordStore.

◆ setKey()

void mongo::PrefixedWiredTigerRecordStore::setKey	(	WT_CURSOR *	cursor,
