BaseObject

The BaseObject is the top-most SuperClass of (most but not) all Classes in orxonox.

source:/trunk/src/lib/lang/base_object.h#HEAD
Derived From:

• nothing

Description

BaseObject is a container for

• The Name of the Object (how the object is called)
• The Class' Name of the Object (in what class this object is)
• The ClassID of the Object (what is the Identity of the class (see ClassID

Usage

• Registration:
  Each class, that extends BaseObject must implement the following function:
  1. In the Class-Declaration use the following syntax (taken your class is named OrxClass)

       class OrxClass : public BaseObject // here you could also specify any class derived from BaseObject
       {
         ObjectListDeclaration(OrxClass);
         /// ... rest of the Declaration;
       };
     

  2. At the top of the cc-file of the Class (in the definiton) write:

       ObjectListDefinition(OrxClass);
     

  3. In the constructor of each class implementing BaseObject write the following:

     this->registerObject(this, OrxClass::_objectList);
     

  4. you can then set a Name to the Object using

     this->setName("the name");
     

• isA:
  isA is a function, that queries, if the Object is of a Specified type. e.g. given a class Player that is derived from BaseObject and PNode one can do the following check :

   Player* player = new Player();
   if (player->isA(PNode::staticClassID()) {
     /* do something terrible with it */ }

An interessting Function, that BaseObject provides is the ObjectList. With it, one can retrieve lists of any one kind of derived classes from BaseObject.
