Allocates memory for each instance of an invokable object.

Pascal
class function NewInstance: TObject; override;
C++
virtual __fastcall TObject * NewInstance();
Description

Constructors call NewInstance automatically. NewInstance calls InstanceSize to determine how much memory to allocate from the heap to contain a particular instance. Do not call NewInstance directly.  

TInvokableClass overrides NewInstance to increment the reference count when a new instance is created. This prevents any constructor from accidentally deleting the instance due to a RefCount of zero. The AfterConstruction method decrements the value of RefCount after all constructors have executed.
