Detailed Description

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

Helper for defining an abstract managed class.

Managed classes are implementations of coherence::lang::Object, and include a set of well known features, which are auto-generated by this helper class:

• Handle/View/Holder definitions
• super class definition
• virtual interface inheritance of up to 16 interfaces

The template takes three parameters:

• The name of the class being defined
• The defined classes parent class, indicated as extends<parent>
• An optional list of interfaces to implement, indicated as implements<i1, i2, ...>

A normal class definition would be:

 class Bar
   : public abstract_spec<Bar,
       extends<Object>,
       implements<SomeInterface, SomeOtherInterface> >
   {
   public:
       // normal abstract class definition....
   };

Constructor & Destructor Documentation

abstract_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.

Member Function Documentation

virtual size32_t sizeOf

(

)

const [pure virtual]

Pure virtual sizeOf definition ensures that the resulting class is abstract.

Reimplemented from class_spec.
