Method Detail

constructProxy

public static Object constructProxy(Object root,
                                    Class iface)

assignStructuralIdentity

public static Object assignStructuralIdentity(Object obj,
                                              Class iface)

invokeUnhandled

public static Object invokeUnhandled(Object thiz,
                                     Class proxiedIface,
                                     String name,
                                     Class returnType,
                                     Class[] paramTypes,
                                     Object[] args)

Facilitates ICallHandler where the receiver of the method call structurally implements a method, but the association of the structural interface with the receiver is lost. For example:

   Person person = Person.create(); // Person is a JsonTypeManifold interface; the runtime type of person here is really just a Map (or Binding)
   IMyStructureThing thing = (IMyStructureThing)person; // Extension method[s] satisfying IMyStructureThing on Person make this work e.g., via MyPersonExt extension methods class
   thing.foo(); // foo() is an extension method on Person e.g., defined in MyPersonExt, however the runtime type of thing is just a Map (or Binding) thus the Person type identity is lost
 

coerce

public static Object coerce(Object value,
                            Class<?> type)
