Minimizing inlines

While inline functions speed execution, they may also increase executable sizes, so that as more inlines are added, the time saved by avoiding function linkage is eventually swamped by the increase in text size. We therefore limited our use of inlines to two cases:

• when the amount of inline code is small

• when the functionality of a frequently-used function can be divided into two parts: a simple case, which is done inline, and a complicated case, which requires a function call. We talk more about this case in the section ``Using inline functions''.

       Block.h
           template <class T> class Block {
           private:
               unsigned n;
               unsigned grow(unsigned);
               ...
           public:
               // example of (1)
               unsigned size() const { return n; }
               // example of (2)
               int reserve(unsigned k) {
                   return k<n || grow(k);
               }
               ...
           }
