CreateElement

Creates a new element of the list.

CObject* CreateElement()

Return Value

Pointer to the newly created element - successful, NULL - cannot create an element.

Note

Method CreateElement () in the CList class always returns NULL and does not perform any actions. If necessary, method CreateElement () should be implemented in a derived class.

Example:

//--- example for CList::CreateElement(int)
#include <Arrays\List.mqh>
//---
void OnStart()
  {
   int    size=100;
   CList *list=new CList;
   //---
   if(list==NULL)
     {
      printf("Object create error");
      return;
     }
   //--- fill list
   for(int i=0;i<size;i++)
     {
      CObject *object=list.CreateElement();
      if(object==NULL)
        {
         printf("Element create error");
         delete list;
         return;
        }
      list.Add(object);
     }
   //--- use list
   //--- . . .
   //--- delete list
   delete list;
  }
