get_list_slotvalues/3—retrieve a list of slots from one or more objects

The get_list_slotvalues/3  function retrieves a list of slots from one or more  objects. The syntax for this function is as follows:

get_list_slotvalues($OBJECTS,$SLOTS,$VALUES)
$VALUES=get_list_slotvlaues($OBJECTS,$SLOTS)

get_list_slotvalues/3 arguments

Use the get_list_slotvalues/3 function to retrieve one or more of the slots specified in the $SLOTS list from the objects in $OBJECTS. The resulting slots are returned in the $VALUES list.

The required slots must be specified in $SLOTS by name, or by reference to an object and the slot name. A reference to a slot of an object has the form $n.SlotName, where n is the sequence number of the required object in $OBJECTS. If the slot is mentioned only by name, with no object reference, it is taken from the first object in the list.

get_list_slotvalues/3 example

$VALUES = get_list_slotvalues([$E,$D],[mc_ueid,status]);

The list $VALUES contains the mc_ueid slot and the status slot from the event object $E.

$VALUES = get_list_slotvalues([$E,$D],
	['$1.mc_ueid','$1.status','$2.mc_udid']);

The list $VALUES contains the mc_ueid slot and the status of the event object $E, and the mc_udid slot of the data object $D.
