void Kross::Api::Event< EventSignal >::addFunction (  const QString &  name,
Function *  function
)  [inline, inherited]
 

Add a methodfunction to the list of functions this Object supports.

Parameters:
name The functionname. Each function this object holds should have an unique name to be still accessable.
function A Function instance which defines the methodfunction. This Event will be the owner of the Function instance and will take care of deleting it if this Event got deleted.

void Kross::Api::Event< EventSignal >::addFunction (  const QString &  name,
FunctionPtr  function,
const ArgumentList &  = ArgumentList()
)  [inline, inherited]
 

Add a Callable methodfunction to the list of functions this Object supports.

The FunctionPtr points to the concret Object::Ptr myfuncname(List::Ptr) method in the class defined with template T.

Parameters:
name The functionname. Each function this object holds should have an unique name to be still accessable.
function A pointer to the methodfunction that should handle calls.
arglist A list of arguments for the function.

Overloaded method to handle function-calls.

Exceptions:
AttributeException if argumentparameters arn't valid.
RuntimeException if the functionname isn't valid.
Parameters:
name The functionname. Each function this Object holds should have a different name cause they are access by they name. If name is QString::null or empty, a self-reference to this instance is returned.
arguments The list of arguments.
Returns:
An Object representing the call result or NULL if there doesn't exists such a function with defined name.

Object::Ptr EventSignal::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.
