CSet:RemoveFirst
The RemoveFirst method removes the member at the head of the list.
|
member = CSet:RemoveFirst() |
member is a reference to the member that was
removed.
On success,
this method returns the removed member.
On failure,
nil is returned.
Removing the list member decreases the list length by 1 member.
Suppose a CSet exists with name S and that it contains 10 values. The following script fragment removes the value at the head of the list:
|
Printf("count=%d", S:Count()) |
-- result: count=10 |
|
S:RemoveFirst() |
-- remove the first member |
|
Printf("count=%d", S:Count()) |
-- result: count=9
