The iterator will be read-only if the collection is read-only.
This method conforms to the <code>Collection.iterator()</code> interface.
<p>The iterator returned by this method does not keep a database cursor
open and therefore it does not need to be closed. It reads blocks of
records as needed, opening and closing a cursor to read each block of
records. The number of records per block is 10 by default and can be
changed with <a href="../../../com/sleepycat/collections/StoredCollection.html#setIteratorBlockSize-int-"><code>setIteratorBlockSize(int)</code></a>.</p>
<p>Because this iterator does not keep a cursor open, if it is used
without transactions, the iterator does not have <em>cursor
stability</em> characteristics. In other words, the record at the
current iterator position can be changed or deleted by another thread.
To prevent this from happening, call this method within a transaction or
