= !ObjectList =
[[TracNav(TracNav/TOC_Development)]]

== Description ==

!ObjectList is a wrapper to [wiki:ObjectListBase]. !ObjectListBase contains all objects of a given class, but threats the objects as [wiki:OrxonoxClass OrxonoxClasses]. !ObjectList in contrary is a template and knows about the correct class. By definition theres only one !ObjectList per class. This is easy to proof because !ObjectList<T> just redirects to ClassIdentifier<T>::''''''''''objects_ (which is an !ObjectListBase).

So, in other words, !ObjectList<T> is just a shortcut for:
{{{
ClassIdentifier<T>::getIdentifier()->getObjects()
}}}

== Functions ==
!ObjectList provides the same functions as !ObjectListBase but doesn't return an [wiki:ObjectListBase#ObjectListBase::Export Export] struct but a class-specific list element pointer which can not only be used by [wiki:Iterator] but also by [wiki:ObjectListIterator]. This is important because !ObjectListIterator is much more performant than Iterator.

 * '''begin()''': Returns a pointer to the first element in the list
 * '''end()''': Returns a pointer to the list-element '''after''' the last element in the list
 * '''rbegin()''': Returns a pointer to the last element in the list
 * '''rend()''': Returns a pointer to the list-element '''before''' the first element in the list

See Iterator and ObjectListIterator for more information about the usage of those functions.
