void caffe2::db::LMDBCursor::Seek ( const string &  key)
inlineoverridevirtual

Seek to a specific key (or if the key does not exist, seek to the immediate next).

This is optional for dbs, and in default, SupportsSeek() returns false meaning that the db cursor does not support it.

Implements caffe2::db::Cursor.
