Templates and inheritance: Double dependancy
Hi all. I am trying to implement a red-black binary tree in terms of of an overloaded binary tree class. The base binary tree class represents the nodes as template <class T> class BinaryTreeNode { T Key_; /* internal fields needed to maintain the tree */ }; template <class T> class BinaryTree ... 4 Jan 2008 13:30

an intrusive smart pointer
hi, I am using an adhoc intrusive templated smart pointer implementation and I stumbled upon a small implementation quirk. details: - intrusive: requires Ref and Unref to be defined on target type - assumes refcount is initialized to one by constructor of target type The above details make it impossible... 6 Jan 2008 11:10

typedef in template class ---GCC3.4.5 vs MSVC8
