<h1>Benefits</h1><p class="MsoNormal">External callbacks help you to solve many different problems
and customize db4o behavior. Among their benefits:</p>
<ul><li><span style="font-family:'Times New Roman';"><span style="font-family:'Times New Roman';font-style:normal;font-variant:normal;font-weight:normal;font-size:7pt;line-height:normal;font-size-adjust:none;font-stretch:normal;"></span></span>With external callbacks you do not have to pollute your
object model with persistence code. This is exceptionally valuable when the
objects are inherited from external application or library.</li><li><span style="font-family:'Times New Roman';"><span style="font-family:'Times New Roman';font-style:normal;font-variant:normal;font-weight:normal;font-size:7pt;line-height:normal;font-size-adjust:none;font-stretch:normal;"></span></span>Multiple event handlers can be registered on particular
events, keeping your code clean and easily readable. </li><li><span style="font-family:'Times New Roman';"><span style="font-family:'Times New Roman';font-style:normal;font-variant:normal;font-weight:normal;font-size:7pt;line-height:normal;font-size-adjust:none;font-stretch:normal;"></span></span>You can "plug-in" different modules to
perform different tasks. An example can be a module responsible for assigning
unique IDs to your objects.<span><o:p></o:p></span></li></ul></div>
