Sure thing. It knows the value of function is the same as the value it passes it, knows the definition of the function, so just replaces the definition inline and calls the function directly. I can’t think of a condition where a compiler won’t inline a one-line function call, it’s just replacing a function call … Read more
It took me quite some time to figure out but it is actually really simple. from django.contrib import admin from django.forms.models import BaseInlineFormSet, ModelForm class AlwaysChangedModelForm(ModelForm): def has_changed(self): “”” Should returns True if data differs from initial. By always returning true even unchanged inlines will get validated and saved.””” return True class CheckerInline(admin.StackedInline): “”” Base … Read more
The non-static inline function declaration refers to the same function in every translation unit (source file) that uses it. The One Definition Rule requires that the body of the function definition is identical in every TU that contains it, with a longish definition of “identical”. This is usually satisfied provided that the source files all … Read more
You need to put function definition into the header then. The simplest way to hint the compiler to inline is to include method body in the class declaration like: class NeedleUSsim { // … int GetTplLSize() const { return sampleDim[1]; } // … }; or, if you insist on separate declaration and definition: class NeedleUSsim … Read more
The former (using inline) allows you to put that function in a header file, where it can be included in multiple source files. Using inline makes the identifier in file scope, much like declaring it static. Without using inline, you would get a multiple symbol definition error from the linker. Of course, this is in … Read more
The definition of an inline function doesn’t have to be in a header file but, because of the one definition rule (ODR) for inline functions, an identical definition for the function must exist in every translation unit that uses it. The easiest way to achieve this is by putting the definition in a header file. … Read more
Advantages By inlining your code where it is needed, your program will spend less time in the function call and return parts. It is supposed to make your code go faster, even as it goes larger (see below). Inlining trivial accessors could be an example of effective inlining. By marking it as inline, you can … Read more
when i read the spec, i find your question actually quite well answered: When an inline box contains a block box, the inline box […] [is] broken around the block. The [in]line boxes before the break and after the break are enclosed in anonymous boxes, and the block box becomes a sibling of those anonymous … Read more
Confusion arises because inline has two effects: It tells the compiler that the function code can be expanded where the function is called, instead of effectively being called. It tells the compiler that the function definition can be repeated. Point 1. is “archaic” in the sense that the compiler can in fact do what it … Read more
Yes. Any compiler is free to inline any function whenever it thinks it is a good idea. GCC does that as well. At -O2 optimization level the inlining is done when the compiler thinks it is worth doing (a heuristic is used) and if it will not increase the size of the code. At -O3 … Read more
