Detailed Description

The common Object class all other object-classes are inheritated from.

The Object class is used as base class to provide common functionality. It's similar to what we know in Python as PyObject or in Qt as QObject.

Inherited from e.g. Value, Module and Class .

This class implementates reference counting for shared objects. So, no need to take care of freeing objects.

virtual Object::Ptr Kross::Api::Object::call const QString name,
KSharedPtr< List arguments
[virtual]
 

Pass a call to the object and evaluated it recursive down the object-hierachy. Objects like Class are able to handle call's by just implementing this function. If the call is done the called() method will be executed recursive from bottom up the call hierachy.

Exceptions:
TypeException if the object or the name is not callable.
Parameters:
name Each call has a name that says what should be called. In the case of a Class the name is the functionname.
arguments The list of arguments passed to the call.
Returns:
The call-result as Object::Ptr instance or NULL if the call has no result.

Reimplemented in Kross::Api::EventScript, Kross::Api::EventSignal, and Kross::Api::EventSlot.

template<class T>
static T* Kross::Api::Object::fromObject Object::Ptr  object  )  [inline, static]
 

Try to convert the Object instance to the template class T.

Exceptions:
TypeException if the cast failed.
Parameters:
object The Object to cast.
Returns:
The to a instance from template type T casted Object.
