global object
Class Method Summary collapse
-
.const_get_name ⇒ Object
Get the constant in the scope of the current cref.
-
.const_lookup_ancestors ⇒ Object
Walk up the ancestors chain looking for the constant.
-
.const_lookup_nesting ⇒ Object
Walk up the nesting array looking for the constant.
-
.const_lookup_Object ⇒ Object
Walk up Object's ancestors chain looking for the constant, but only if cref is missing or a module.
-
.const_missing ⇒ Object
Call const_missing if nothing else worked.
-
