There is nothing that prevents you to put inline in a static function in a .cpp file. Some compilers have the option to force an inline function, see e.g. the GCC attribute((always_inline)) and a ton of options to fine tune the inlining optimizations (see -minline-* parameters). My recommendation is to use inline or even better … Read more
When you declare a friend function with an unqualified id in a class it names a function in the nearest enclosing namespace scope. If that function hasn’t previously been declared then the friend declaration doesn’t make that function visible in that scope for normal lookup. It does make the declared function visible to argument-dependent lookup. … Read more
In C (as opposed to C++) there’s no standard way to suggest that a function should be inlined. It’s only vender-specific extensions. However you specify it, as far as I know the compiler will always try to inline every instance, so use that function only once: original: int MyFunc() { /* do stuff */ } … Read more
Maybe a few examples would help. 1. Traditional compiled library foo.h: extern int x; int * f(); foo.cpp: #include “foo.h” int x = 25; int * f() { return &x; } Users include foo.h and need to link in the translation unit containing foo.cpp in order to call f. Every such call returns the same … Read more
Use RichText class var text = new RichText( text: new TextSpan( // Note: Styles for TextSpans must be explicitly defined. // Child text spans will inherit styles from parent style: new TextStyle( fontSize: 14.0, color: Colors.black, ), children: <TextSpan>[ new TextSpan(text: ‘Hello’), new TextSpan(text: ‘World’, style: new TextStyle(fontWeight: FontWeight.bold)), ], ), );
__inline__ is a non-standard extension. Typically, it tells the compiler: “inline this function”, but being a non-standard extension we can’t say with certainty unless we know which compiler this is on. To inline is to remove the function call and place it’s contents directly where the call would be made. This often removes the overhead … Read more
‘<option value=”‘ + col + ‘”‘+ (col === “screwdriver” ? ” selected ” : “”) +’>Very roomy</option>’;
Never @inline anything whose implementation might reasonably change and which is going to be a public part of a library. When I say “implementation change” I mean that the logic actually might change. For example: object TradeComparator extends java.lang.Comparator[Trade] { @inline def compare(t1 : Trade, t2 : Trade) Int = t1.time compare t2.time } Let’s … Read more
Calling an inline function may or may not generate a function call, which typically incurs a very small amount of overhead. The exact situations under which an inline function actually gets inlined vary depending on the compiler; most make a good-faith effort to inline small functions (at least when optimization is enabled), but there is … Read more
One solution that is often mentioned is to add the image as an Attachment to the mail, and then reference it in the HTML mailbody using a cid: reference. However if you use the LinkedResources collection instead, the inline images will still appear just fine, but don’t show as additional attachments to the mail. That’s … Read more
