Interface Template
Part of TemplatesCategory
Description
Shows how to use an interface template
Example
It wasn't mentioned in the docs, but I had a slight inkling that it might be the case that one could have InterfaceTemplates using the same syntax as ClassTemplates (ie class ClassName?(T) : ![superclass [, interfaces] ). The following example compiled and ran correctly, outputting "1\n4\n" as expected. Perhaps this warrants a mention in the documentation under Templates, alongside "Class Templates"?
interface Foo(T) { int aFunction(T anArgument); } class Bar(T) : Foo!(T) { int aFunction(T anArgument) { return anArgument.size; } } int main(char[][] args) { Bar!(ubyte) one = new Bar!(ubyte); Bar!(int) two = new Bar!(int); ubyte oneVar = 16; int twoVar = 400000; printf("%i\n%i\n", one.aFunction(oneVar), two.aFunction(twoVar)); return 0; }
