The base class for all types in Qore expression trees that cannot throw an exception when deleted.
This class adds the deref() function without an ExceptionSink argument.
| DLLEXPORT void AbstractQoreNode::deref |
decrements the reference count and deletes the object when references = 0
This function is not virtual and should be used when possible for SimpleQoreNode objects
