string	$signalName	Name of the signal
mixed	$slotClassNameOrObject	Name of the class containing the slot or the instantiated class or a Closure object
string	$slotMethodName	Name of the method to be used as a slot. If $slotClassNameOrObject is a Closure object, this parameter is ignored

		array	$signalArguments = array()

Parameters

string	$signalClassName	Name of the class containing the signal
string	$signalName	Name of the signal

getSlots	(		$signalClassName,
			$signalName
	)

Parameters

Returns

array An array of arrays with slot information

initializeObject
