BOOST_STATIC_ASSERT asserts at compile time which is very helpful both for testing preconditions and enforcing other requirements. For generic programming checked_delete is extremely helpful in detecting erroneous usage which in turn can save a lot of time reading terribly verbose error messages and studying code that seems just fine. We have also covered addressof which is a handy tool for getting to the real address of an object regardless of what operator says. We also saw how enable_if and disable_if can control which functions participate in overload resolution and learned what SFINAE means We talked about the base class noncopyable. By providing both a useful idiom and straightforward usage that catches the eye of anyone reading the code it definitely deserves to be used regularly. The omission of a copy constructor and assignment operator in classes that need them whether through the need for customized copying assignment or the prohibition thereof is all too common in code costing lots of frustration time and money. This is one of the shortest chapters in the book and I suspect that you ve read through it fairly quickly. It pays you back fast too if you start using these utilities right away. There are other utilities in which I haven t covered here. You might want to surf over to the Boost Web site and have a look at the online documentation to see what other handy tools there would suit you well in your current work. How Does the Operators Library Improve Your Programs Provides a complete set of comparison operators Provides a complete set of arithmetic operators Provides a complete set of operators for iterators Among the operators defined in C there are a number of related sets. When you encounter a class with one operator from one of these sets you typically expect to find the others too. For instance when a class provides .
