The newly-allocated hash table may now have data stored and retrieved. Efforts to store more than <code>$table_size</code> elements will result in a fatal error, as will efforts to store a value not exactly <code>$value_len</code> characters in length, or reference through a key not exactly <code>$key_len</code> characters in length. While these constraints may seem excessive, the result is a hash table using much less internal memory than an equivalent freely-allocated hash table.</p> <h1 id="CAVEATS"><a class="permalink" href="#CAVEATS">#</a>CAVEATS</h1> <p>Because the current implementation uses the table and key sizes for the hashing algorithm, there is no means by which to dynamically change the value of any of the initialization parameters.</p> <p>The hash does not support exists().</p> </div> <div id="footer"> <p>Perldoc Browser is maintained by Dan Book (<a href="https://metacpan.org/author/DBOOK">DBOOK</a>).
