Detailed Description

dummy base of interface types

usage:

// declare an interface
zfinterface YourInterface : zfextend ZFInterface {
    ZFINTERFACE_DECLARE(YourInterface, ZFInterface)
};
 
// implement an interface
zfclass YourType : zfextend ZFObject
                 , zfimplement YourInterface
                 , zfimplement ParentInterface1
                 , zfimplement ParentInterface2
                 ...
{
    ZFOBJECT_DECLARE(YourType, ZFObject)
    ZFIMPLEMENT_DECLARE(YourInterface, ParentInterface1, ParentInterface2, ...)
};

(ZFTAG_LIMITATION) due to some limitations of C++ (basically the limitations of diamond inheritance), you should remember these while using interface:

• an interface must inherit from ZFInterface or other interface (at most one), it can only be "implemented" by a "ZFObject type"
• you must have ZFINTERFACE_DECLARE declared in your interface, and must have ZFIMPLEMENT_DECLARE declared in your child type that implement the interface

ADVANCED:
to simulate a interface that inherit from multiple interfaces, you should do it like this:
Java code:

public interface IParent0 {}
public interface IParent1 {}
public interface IChild extends IParent0, IParent1 {}
public class ObjParent implements IParent0 {}
public class ObjChild extends ObjParent implements IChild {}

equivalent code for ZFInterface:

zfinterface IParent0 : zfextend ZFInterface {
    ZFINTERFACE_DECLARE(IParent0, ZFInterface)
};
zfinterface IParent1 : zfextend ZFInterface {
    ZFINTERFACE_DECLARE(IParent1, ZFInterface)
};
zfinterface IChild : zfextend IParent0 { // note: can only inherit at most one parent interface
    ZFINTERFACE_DECLARE(IChild, IParent0)
};
zfclass ObjParent : zfextend ZFObject, zfimplement IParent0 {
    ZFOBJECT_DECLARE(ObjParent, ZFObject)
    ZFIMPLEMENT_DECLARE(IParent0)
};
zfclass ObjChild : zfextend ObjParent, zfimplement IChild
                 , zfimplement IParent1 // note: here is required
{
    ZFOBJECT_DECLARE(ObjChild, ObjParent)
    ZFIMPLEMENT_DECLARE(IChild
            , IParent1 // note: here is required
            )
};

it's strongly recommend not to make interface inherit multiple interfaces
