Class: ObjectSpace::InternalObjectWrapper

Relationships & Source Files
Inherits: Object
Defined in: ext/objspace/objspace.c

Overview

InternalObjectWrapper wraps objects that are internal to the CRuby implementation and usually not directly visible in Ruby code.

reachable_objects_from and reachable_objects_from_root return instances of this class when a reachable object is an internal object. Some other ::ObjectSpace methods, such as internal_super_of, may also return wrapped internal objects.

An InternalObjectWrapper is a debugging and introspection object. Do not use it in application code. The wrapped object and the exact details of this class are implementation specific and may change in future versions.

static VALUE
iow_inspect(VALUE self)
{
    VALUE obj = (VALUE)DATA_PTR(self);
    VALUE type = type2sym(BUILTIN_TYPE(obj));

    return rb_sprintf("#<InternalObject:%p %"PRIsVALUE">", (void *)obj, rb_sym2str(type));

    #internal_object_id  ⇒ Integer   



  

    
Returns the Object#object_id of the wrapped internal object.


This value identifies the wrapped internal object, not the
InternalObjectWrapper instance. Use it only for debugging and
introspection; object ids of internal objects are implementation specific.

static VALUE
iow_internal_object_id(VALUE self)
{
    VALUE obj = (VALUE)DATA_PTR(self);
    return rb_obj_id(obj);
}


  








  

    #type  ⇒ Symbol   



  

    
Returns the type of the wrapped internal object as a symbol.


For example, an included module is represented internally as a T_ICLASS
object:


require 'objspace'

module M; end
class A; include M; end

iclass = ObjectSpace.internal_super_of(A)
iclass.type # => :T_ICLASS


The exact set of returned symbols is implementation specific.
