Using container

ZFFramework use these container types:

• all other C++ containers, such as std::vector, can be used directly
• ZFCoreArray/ZFCoreMap
  C++-style container similar to std::vector / std::map, may not so efficient compared to STL containers, used to reduce dependency, use only if necessary

  ZFCoreArray<zfstring> array;
  array.add("element");
  const zfstring &e = array[0];
   
  ZFCoreMap map;
  // can hold string as key type and any type as value type,
  // while value type can only be wrapped by ZFCorePointer
  zfstring *p = zfnew(zfstring);
  map.set("key", ZFCorePointerForObject<zfstring *>(p));
  // see #ZFCorePointer and #ZFCoreMap for more info

• ZFContainer/ZFKeyValueContainer
  container as ZFObject, can hold ZFObject types only
  typically we have ZFArray, ZFSet, ZFHashSet as container, and ZFMap, ZFHashMap as key value container
  all container would automatically retain elements when add, and release when remove

  zfobj<ZFArray> array;
   
  // can hold ZFObject types only
  array->add(zfobj<v_zfstring>());
