I never realised that the RexxInteger has a (what? metaclass?) different from
RexxClass.…
And apparently, it’s the only class to be like that.
My notes:
All classes declare they class using CLASS_CREATE
except RexxInteger and NumberString which use CLASS_CREATE_SPECIAL
and except RexxClass, probably for bootstrap.
CLASS_CREATE_SPECIAL(NumberString, "String", RexxClass);
CLASS_CREATE_SPECIAL(Integer, "String", RexxIntegerClass);
RexxClass *NumberString::classInstance = OREF_NULL;
RexxIntegerClass *RexxInteger::classInstance = OREF_NULL;
Only the file IntegerClass.cpp has 2 live methods:
void RexxInteger::live(size_t liveMark)
void RexxIntegerClass::live(size_t liveMark)
I noticed that all the class are doing
memory_mark(objectVariables);
instead of doing
RexxObject::live(liveMark)
This is aligned with the comment in ObjectClass.cpp
* Other exported classes that inherit from Object are
* also expected to mark this field.
but to not forget if other attributes are added to RexxObject in the future.
