#define MIRROR_OBJECT_TAG

(

TAG

)

Expands into an instantiation of the tag template for the TAG.

This macro expands into an instantiation of the tag template class for the TAG previously registered with the MIRROR_REG_OBJECT_TAG macro.

MIRROR_REG_OBJECT_TAG

MIRROR_TAG_TYPE

Examples:

mirror/example/meta_prog_06.cpp.

#define MIRROR_REG_OBJECT_TAG

(

TAG

)

This macro registers a new tag for tagging reflected objects.

Once registered tags can be used to tag the objects reflected by Mirror. For example one can assign a single_instance tag to a class or a unique tag to a class member variable, etc.

See also:

MIRROR_OBJECT_TAG

#define MIRROR_TAG_TYPE	(		TYPE,
			TAGS
	)

Value:

namespace tagsel { \
template <> \
struct type_tags< TYPE > \
{ \
    typedef mirror::mp::range< \
        MIRROR_PP_EXPAND_ARGS TAGS \
    > type; \
}; \
}

Assigns the list of TAGS to the TYPE.

This macro assigns the comma separated list of TAGS (enclosed in parentheses) to the type specified by the TYPE argument.

All the tags must be registered with the MIRROR_REG_OBJECT_TAG macro before they can be used.
