Retrieve last Arraylist item, then remove item (Arraylist class)
Pop is a member of the Arraylist class.
This callable function returns the current contents of the last item in the method object Arraylist; then it removes that item.
Pop is available in Sirius Mods version 7.0 and later.
Syntax
[%item =] al:Pop
Syntax terms
| %item | A variable of the same type as specified on the al declaration to contain the contents of the last al item. |
|---|---|
| al | An Arraylist object. |
Usage notes
- The Pop method for object al is equivalent to specifying al:Item(al:Count) followed by al:RemoveItem(al:Count).
- LastItem returns the last item of an Arraylist without removing it. Dequeue returns the first item of an Arraylist, then removes it.
- The Push function, a synonym for Add, appends an item to an Arraylist.
