Sorry about that.
string ATypeGenerator( string name ) {
return "class " ~ name ~ " : ClassC {
private:
U value;
public:
this(){}
void print(){}
mixin V;
}";
}
mixin template AType( string name, U, alias V ) {
mixin( ATypeGenerator( name ) );
}
class ClassC {}
mixin template btype() {
void someFunction() {}; // Content of a class.
}
mixin AType!("ClassB", string, btype);
void main() {
ClassC r = new ClassB();
}
