From e03d6d9eb84764cb854dc500ce8c19d85db53656 Mon Sep 17 00:00:00 2001 From: ko1 Date: Fri, 5 Oct 2012 08:14:09 +0000 Subject: * ext/objspace/objspace.c: add ObjectSpace#reachable_objects_from. This method returns an array of objects referenced by given object. If given object is special objects such as true/false/nil/Fixnum etc then it returns nil. See rdoc for details. [ruby-core:39772] * test/objspace/test_objspace.rb: add a test for this method. * gc.c: add rb_objspace_reachable_objects_from(). To make this function, add several member `mark_func_data' to rb_objspace_t. If mark_func_data is not null, then gc_mark() calls mark_func_data::mark_func. * gc.h: export rb_objspace_reachable_objects_from(). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37094 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- gc.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'gc.h') diff --git a/gc.h b/gc.h index 96d22a6e09..741945349d 100644 --- a/gc.h +++ b/gc.h @@ -87,7 +87,10 @@ int ruby_get_stack_grow_direction(volatile VALUE *addr); #pragma GCC visibility push(default) #endif +/* exports for objspace module */ size_t rb_objspace_data_type_memsize(VALUE obj); +VALUE rb_objspace_reachable_objects_from(VALUE obj); + void rb_objspace_each_objects( int (*callback)(void *start, void *end, size_t stride, void *data), void *data); -- cgit v1.2.3
