Any way to reload or rebuild a class with different methods/member data?

<div class="jive-rendered-content"><p>I can successfully create class definitions at runtime using Javassist, but I also need the ability to rebuild the definitions to add/remove/change member data and their getters/setters. Is this at all possible? I'm using a custom class loader for the classes that I generate. I was hoping I could do something like this:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>- create class definition in custom class pool (<a class="jive-link-external-small" href="http://www.csg.ci.i.u-tokyo.ac.jp/~chiba/javassist/html/javassist/ClassPool.html#ClassPool(javassist.ClassPool)" rel="nofollow">ClassPool</a>(<a class="jive-link-external-small" href="http://www.csg.ci.i.u-tokyo.ac.jp/~chiba/javassist/html/javassist/ClassPool.html" rel="nofollow">ClassPool</a> parent))</p><p>- add to custom class loader</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Then later:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>- retrieve CtClass instance and detach it from the pool</p><p>- remove from custom class loader</p><p>- create new class definition with the same class path</p><p>- add to same custom class loader</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Or alternatively:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>- retrieve CtClass instance and detach it from the pool</p><p>- remove all fields and methods</p><p>- create new fields and methods</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Is this at all possible? Thanks</p></div>
