Does c++ not “specialize” in one location like FPC? looking at c++ code I
often see things like Vector<x> used in multiple locations instead of declaring
a single type (I have no idea why they would do that but it’s very common).
Maybe that’s why compile times are so slow?
In one instance I did something similar but hopefully it “unfolds” only once
when the unit compiles. Is that true?
type
generic TStaticArray<T> = class (TObject)
end;
type
generic TDynamicArray<T> = class (specialize TStaticArray<T>)
end;
type
generic TGenericArray<T> = class (specialize TDynamicArray<T>)
end;
type
TIntegerArray = specialize TGenericArray<Integer>;
TLongIntArray = specialize TGenericArray<LongInt>;
TStringArray = specialize TGenericArray<String>;
TSingleArray = specialize TGenericArray<Single>;
TDoubleArray = specialize TGenericArray<Double>;
TFloatArray = specialize TGenericArray<TFloat>;
TPointerArray = specialize TGenericArray<Pointer>;
