Detailed Description

the implementation of Qore's object data type, reference counted, dynamically-allocated only

objects in Qore are unique unless copied explicitly (similar to Java) Builtin classes (those classes implemented in C++ as opposed to user classes implemented in the Qore language) can have "private data", which is data that maintains the state of the object per that class. QoreObject objects store this data as well as any member data.

objects have two levels of reference counts - one is for the existence of the c++ object (tRefs below) the other is for the scope of the object (the parent QoreReferenceCounter) - when this reaches 0 the object will have its destructor run (if it hasn't already been deleted). Only when the tRef counter reaches 0, meaning that no more pointers are pointing to this object will the object actually be deleted.
