Thank you,
the closest implementation I found is here
PlasticManager plasticManager =
PlasticManager.withContextClassLoader().create();
PlasticClass plasticClass =
plasticManager.createProxyTransformation(serviceInterface,
null).getPlasticClass();
PlasticField plasticField =
plasticClass.introduceField(IProvider.class, "_creator");
PlasticProxyFactory factory = new
PlasticProxyFactoryImpl(plasticManager, log);
MethodDescription methodDescription = new
MethodDescription(serviceInterface.getClass().getName(), "_scopeInstance",
null, null);
plasticClass.introduceMethod(methodDescription);
this doesn't help me to create class instance on the fly though, it is
creates PlasticClass also I didn't find flexibility to specify field access
specifiers
I must be looking at wrong set of class it seems, any thoughts ?
