Delphi2Cpp: Dynamic arrays, conversion from Delphi to C++

This article can be obsolete: Actual documentation online

Dynamic arrays

Dynamic array are simulated in the CBuilder C++ by the class DynamicArray:

template <class T> class DELPHIRETURN DynamicArray;

MyFlexibleArray: array of Real;
->
DynamicArray < double > MyFlexibleArray;

This class has the properties "Low", "High" and "Length". By the "Length" property, the size of the array can be changed.

A Delphi function accepts a dynamic array as parameter, if it is defined explicitely:

type
strarray = Array of String;
procedure Check(aSources : strarray);
->
typedef DynamicArray < String > strarray;
void __fastcall Check( const strarray & aSources, int aSources_high );

In this case Delphi2Cpp translates such a parameter as a reference to a dynamic array. The parameter is translated like an open array however, if the type isn't defined explicitely.
