Detailed Description

Classes in this group inherit from RWCollectable. These classes contain virtual functions for identifying, hashing, comparing, storing, and retrieving collectable objects.

Macro Definition Documentation

RW_DECLARE_ABSTRACT_COLLECTABLE_CLASS

#define RW_DECLARE_ABSTRACT_COLLECTABLE_CLASS	(		libName,
			className )

The macro RW_DECLARE_ABSTRACT_COLLECTABLE_CLASS should be used in the declaration of any abstract class that derives from RWCollectable.

RW_DECLARE_COLLECTABLE_CLASS

#define RW_DECLARE_COLLECTABLE_CLASS	(		libName,
			className )

The macro RW_DECLARE_COLLECTABLE_CLASS should be used in the declaration of any class that derives from RWCollectable.

RW_DEFINE_COLLECTABLE_CLASS_BY_ID

RW_DEFINE_COLLECTABLE_CLASS_BY_NAME

RW_DEFINE_ABSTRACT_COLLECTABLE_CLASS

#define RW_DEFINE_ABSTRACT_COLLECTABLE_CLASS	(		libName,
			className )

The macro RW_DEFINE_ABSTRACT_COLLECTABLE_CLASS should be used in the definition of any abstract class that derives from RWCollectable.

RW_DEFINE_COLLECTABLE_CLASS_BY_ID

#define RW_DEFINE_COLLECTABLE_CLASS_BY_ID	(		libName,
			className,
			id )

The macro RW_DEFINE_COLLECTABLE_CLASS_BY_ID should only be used when your class needs to have the same collectable ID or for compatibility with older versions of Tools.h++.

If you use this macro, you will be defining an RWClassID that is forever associated with your class.

Example

#include <rw/collect.h>
 
// See the section in the Essential Tools Module User's Guide
// about exporting symbols for more information about this macro.
#define EXPORT
 
class MyCollectable1 : public RWCollectable {
  RW_DECLARE_COLLECTABLE_CLASS(EXPORT, MyCollectable1);
};
 
RW_DEFINE_COLLECTABLE_CLASS_BY_ID(EXPORT, MyCollectable1, 0x1000)

RW_DECLARE_COLLECTABLE_CLASS

RW_DEFINE_COLLECTABLE_CLASS_BY_NAME

#define RW_DEFINE_COLLECTABLE_CLASS_BY_NAME	(		libName,
			className,
			str )

The macro RW_DEFINE_COLLECTABLE_CLASS_BY_NAME should be used in the definition of any class that derives from RWCollectable that doesn't use RW_DEFINE_COLLECTABLE_CLASS_BY_ID.

If you use this macro, your class may have a different RWClassID with each run, but it will be forever associated with the given RWStringID.

Example

#include <rw/collect.h>
 
// See the section in the Essential Tools Module User's Guide
// about exporting symbols for more information about this macro.
#define EXPORT
 
class MyCollectable2 : public RWCollectable {
  RW_DECLARE_COLLECTABLE_CLASS(EXPORT, MyCollectable2);
};
 
RW_DEFINE_COLLECTABLE_CLASS_BY_NAME(EXPORT, MyCollectable2,
                                    "Second Collectable")
