-2 Object system implementation -

-First, to get things clear, what are considered objects here are C -structures containing a properly initialised -structure defined in ioncore/obj.h as the first element (or the -first element of the structure which is the first element and so on which -gives rise to inheritance). The WObj structure contains a pointer -to a WObjDescr class type info structure and -a list of so called ``watches''. The WObjDescr structure simply -lists the class name, a table of dynamic functions and a pointer to -deinitialisation function (or ``destructor''). - -

-Ion does not do any reference counting, garbage collecting or other -fancy things related to automatic safe freeing of objects with its -simplistic object system. Instead special watches (the WWatch - structure) may be used to create safe references to -objects that might be destroyed during the time the specific pointer is -needed. When an object is destroyed, its list of watches is processed, -setting the pointers in the watches to NULL and the watch handlers for -each watch are called. - -
