#define | RB_NEWOBJ(obj, type) type *(obj) = RBIMPL_CAST((type *)rb_newobj()) |
Declares, allocates, then assigns a new object to the given variable. | |
#define | RB_NEWOBJ_OF(obj, type, klass, flags) type *(obj) = RBIMPL_CAST((type *)rb_newobj_of(klass, flags)) |
Identical to RB_NEWOBJ, except it also accepts the allocating object's class and flags. | |
#define | NEWOBJ RB_NEWOBJ |
Old name of RB_NEWOBJ. | |
#define | NEWOBJ_OF RB_NEWOBJ_OF |
Old name of RB_NEWOBJ_OF. | |
#define | OBJSETUP rb_obj_setup |
Old name of rb_obj_setup. | |
#define | CLONESETUP rb_clone_setup |

Functions | |
VALUE | rb_newobj (void) |
This is the implementation detail of RB_NEWOBJ. | |
VALUE | rb_newobj_of (VALUE klass, VALUE flags) |

VALUE | rb_obj_setup (VALUE obj, VALUE klass, VALUE type) |
Fills common fields in the object. | |
VALUE | rb_obj_class (VALUE obj) |
Queries the class of an object. | |
VALUE | rb_singleton_class_clone (VALUE obj) |
Clones a singleton class. | |
void | rb_singleton_class_attached (VALUE klass, VALUE obj) |

void | rb_copy_generic_ivar (VALUE clone, VALUE obj) |
Copies the list of instance variables. | |
static void | rb_clone_setup (VALUE clone, VALUE obj) |
static void | rb_dup_setup (VALUE dup, VALUE obj) |
Defines NEWOBJ.
RBIMPL
or rbimpl
are implementation details. Don't take them as canon. They could rapidly appear then vanish. The name (path) of this header file is also an implementation detail. Do not expect it to persist at the place it is now. Developers are free to move it anywhere anytime at will. __VA_ARGS__
is always available. We assume C99 for ruby itself but we don't assume languages of extension libraries. They could be written in C++98. Definition in file newobj.h.

#define RB_NEWOBJ_OF | ( | obj, | |
type, | |||
klass, | |||

Identical to RB_NEWOBJ, except it also accepts the allocating object's class and flags.
obj | Variable name. |
type | Variable type. |
klass | Object's class. |
flags | Object's flags. |
rb_eNoMemError | No space left. |
Object#clone
stopped using this function. It remained untouched for a while, and then @shyouhei realised that they are no longer doing the same thing. It seems nobody seriously uses this function any longer. Let's just abandon it.[out] | clone | The destination object. |
[in] | obj | The source object. |
Copies the list of instance variables.
3rd parties need not know, but there are several ways to store an object's instance variables, depending on its internal structure. This function makes sense when either of the passed objects are using so-called "generic" backend storage. This distinction is purely an implementation detail of rb_clone_setup(). People need not be aware of this working behind-the-scenes.
[out] | clone | The destination object. |
[in] | obj | The source object. |
