44 </p><p><strong>Bond</strong> class is derived from <strong>ObjectProperty</strong> base class which provides methods not explicitly
45 defined in <strong>Atom</strong> or <strong>ObjectProperty</strong> class using Perl's AUTOLOAD functionality. These methods
46 are generated on-the-fly for a specified object property:</p>
47 <div class="OptionsBox">
48 Set&lt;PropertyName&gt;(&lt;PropertyValue&gt;);
49 <br/> $PropertyValue = Get&lt;PropertyName&gt;();
50 <br/> Delete&lt;PropertyName&gt;();</div>
51 <p>
52 </p>
53 <h2>METHODS</h2>
54 <dl>
55 <dt><strong><a name="new" class="item"><strong>new</strong></a></strong></dt>
56 <dd>
57 <div class="OptionsBox">
58 $NewBond = new Bond([%PropertyNameAndValues]);</div>
59 <p>Using specified <em>Bond</em> property names and values hash, <strong>new</strong> method creates a new object
60 and returns a reference to newly created <strong>Bond</strong> object. By default, following properties are
61 initialized:</p>
62 <div class="OptionsBox">
63 ID = SequentialObjectID
64 <br/> @Atoms = ();
65 <br/> BondType = &quot;&quot;
66 <br/> BondOrder = &quot;&quot;</div>
67 <p>Except for <em>ID</em> property, all other default properties and other additional properties can
68 be set during invocation of this method.</p>
69 <p>Examples:</p>
70 <div class="OptionsBox">
71 $Bond = new Bond();
72 <br/> $DoubleBond = new Bond('Atoms' =&gt; [$Atom2, $Atom1],
73 'BondOrder' =&gt; 2);</div>
