Move to prior entry, populating this iterator with the entry data.
The delta indicates how many moves backward should occur.The most common delta is 1 to move to the prior entry.
Implementations must populate the following members:
{@link #mode}
{@link #path} (from {@link #pathOffset} to {@link #pathLen})
{@link #pathLen}
as well as any implementation dependent information necessary to accurately return data from {@link #idBuffer()} and {@link #idOffset()}when demanded.
@param delta number of entries to move the iterator by. Must be a positive, non-zero integer.
@throws CorruptObjectException the tree is invalid.
Back up one character. This provides a sort of lookahead capability, so that you can test for a digit or letter before attempting to parse the next number or identifier.
