The TFile Scanner. The Scanner has an implicit cursor, which, upon creation, points to the first key-value pair in the scan range. If the scan range is empty, the cursor will point to the end of the scan range.

Use {@link Scanner#atEnd()} to test whether the cursor is at the end location of the scanner.

Use {@link Scanner#advance()} to move the cursor to the next key-value pair (or end if none exists). Use seekTo methods ( {@link Scanner#seekTo(byte[])}or {@link Scanner#seekTo(byte[],int,int)}) to seek to any arbitrary location in the covered range (including backward seeking). Use {@link Scanner#rewind()} to seek back to the beginning of the scanner. Use {@link Scanner#seekToEnd()} to seek to the end of the scanner.

Actual keys and values may be obtained through {@link Scanner.Entry} object, which is obtained through {@link Scanner#entry()}.
