Data Access Item objects contained by group
Item is a vector of daitem objects contained by the dagroup object. Item is initially an empty vector. The size of Item increases as you add items with the additem function, and decreases as you remove items with the delete function.
The default value is an empty matrix ().
This example creates a fictitious client, adds a group and two items.
da = opcda('localhost', 'Dummy.Server'); grp = addgroup(da, 'MyGroup'); itm1 = additem(grp, 'Item.Name.1'); itm2 = additem(grp, 'Item.Name.2'); allItems = grp.Item
If one of the items is deleted, the Item property is updated to reflect this.
delete(itm2); newItems = grp.Item
