SMARTARRAY: A C++ class template for self-describing, resizable, error-resistant arrays

摘要

The SmartArray class template supports one-dimensional (single index) arrays and provides four major features that make it superior to built-in C++ arrays: a SmartArray is self-describing (both capacity and content), a SmartArray can be dynamically resized, the index supplied to the operator of a SmartArray is bounds checked, and the lower bound of a SmartArray can be chosen by the programmer. Additionally, the SmartArray class provides a full set of traversal functions, an assignment operator, editing functions, and an error handling mechanism-yet remains small, self-contained, portable, efficient, and easy to master. The class template SmartArray requires that T be either a built-in type or a class that provides an assignment operator, a default (no argument) constructor, a copy constructor, and a destructor. If T does not contain any pointers, the compiler-generated versions of these four functions will probably be adequate.
