10.2.1.2   Optimization

Optimization might be necessary for variables of class HTuple. This kind of optimization can either be done in HDevelop or in the generated C++ code. In most cases, optimization is not necessary if you program according to the following rules.

• Using the tuple concatenation, it is more efficient to extend a tuple at the “right” side, like:

    T := [T,New]
  

  because this can be transformed to

    T = T.TupleConcat(New);
  

  in C++ and requires no creation of a new tuple, whereas

    T := [New,T]
  

  which is translated into

    T = HTuple(New).TupleConcat(T);
  

  would need the creation of a new tuple.

• Another good way to modify a tuple is the operator assign_at (see section “Assignment”). In this case, HDevelop code like

    T[i] := New
  

  can directly be translated into the efficient and similar looking code

    T[i] = New;
