Detailed Description

template<class T, class E = extends<Object>, class I = implements<>>
class coherence::lang::cloneable_spec< T, E, I >

Helper for defining a cloneable managed class.

It addition to the features auto-generated by the class_spec<> helper template cloneable_spec<> auto-generates an implementation of "Object::Handle clone() const" which delegates to the defined classes const copy constructor.

A normal cloneable class definition would be:

 class Foo
   : public cloneable_spec<Foo,
       extends<Bar>,
       implements<SomeInterface, SomeOtherInterface> >
   {
   // add support for auto-generated static create methods
   friend class factory<Foo>;

   protected:
       // Constructors are defined as protected, and access via
       // auto-generated create methods, with matching signatures
       Foo()
           : super() ...
           {
           }

       // Copy constructor
       Foo(const Foo& that)
           : super(that) ...
           {
           }

   public:
       // normal class definition....
   };

cloneable_spec

(

)

[inline, protected]

Generate a set of proxy constructors matching the signatures of the parent class's constructors.

NOTE: Compilation errors referencing this line likely indicate that class being defined by this spec makes calls a "super" constructor supplying a set of parameters for which there is no exact match on the parent class.
