General Info: Inline Routines

Instead of calling a routine, you move the code from the routine itself and expand it in place of the call. In addition to manual inlining, some languages support automatic inlining where the compiler or some other pre-compiler decides when to inline a code routine. Also, some languages allow for developer defined inlining where the developer can suggest and/or force the inlining of a code routine. Inlining can optimize your code for speed by saving a call and return, and parameter management.

Languages Focus: Inlining

Does it support inlining? If so, does it support developer defined inlining? Does it support automatic inlining? Both?

C++ Inlining

In both Visual C++ and C++Builder, use the inline (standard C++) or __inline (standard C and C++) keywords to suggest to the compiler to inline a routine.

Microsoft also offers __forceinline and _inline, Microsoft specific specifiers where __forceinline is a stronger suggestion but still does not always mean the routine will be inlined as well as _inline for backward compatibility.

Syntax Example:

inline int add(int p1, int p2) {
  int result;

  result = p1 + p2;
  return result;
};

Comment 1 of 1

I usually inline all simple accessor (get/set) methods in C++. If you are concerned about performance, this is a much better approach than making members (instance variables) public. By inlining an accessor, you get the performance of direct access to public members but retain the benefits of encapsulation. Should your simple accessor method grow in complexity, you can easily change your strategy in one place rather than having to find and modify every reference to a public member.
