delete - Remove OPC Toolbox objects from memory
Syntax
delete(Obj)
Description
delete(Obj) removes the OPC Toolbox object Obj from
memory. Obj can be an array of objects. A deleted
object becomes invalid and you should remove references to that object
from the workspace with the clear command.
Deleting an object that contains children (groups or items) also deletes
these children, so you should remove references to these children.
If multiple references to a toolbox object exist in the workspace,
then deleting one object invalidates the remaining references.
If Obj is an opcda object
connected to the server, delete disconnects and
deletes the object.
Examples
Delete a group and its children from memory:
da = opcda('localhost','Matrikon.OPC.Simulation');
connect(da);
grp = addgroup(da,'DeleteEx');
itm = additem(grp,'Random.Real4');
r = read(grp)
delete(grp); % deletes itm as well
clear grp itm
