Examples of javassist.CtClass.toClass()

javassist.CtClass.toClass()
Converts this class to a java.lang.Class object. Once this method is called, further modifications are not allowed any more. To load the class, this method uses the context class loader of the current thread. If the program is running on some application server, the context class loader might be inappropriate to load the class.
This method is provided for convenience. If you need more complex functionality, you should write your own class loader.
Note: this method calls toClass() in ClassPool.
Warining: A Class object returned by this method may not work with a security manager or a signed jar file because a protection domain is not specified. @see #toClass(java.lang.ClassLoader,ProtectionDomain) @see ClassPool#toClass(CtClass)
