You cannot use the
timeout
value when accessing the data queue from a remote node (you can
only use the
timeout
value while adding data to the local data queue).
The
timeout
value is ignored if the data queue is not full.
The
dataqueue.add()
function returns
false
:
•
If the timeout expires before space is available in the data queue
•
If the data queue is full and a
timeout
value is not specified
If the value is a table, a duplicate of the table and any subtables is made. The duplicate table does
not contain any references to the original table or to any subtables.
Example
dataqueue.clear()
dataqueue.add(10)
dataqueue.add(11, 2)
result = dataqueue.add(12, 3)
if result == false then
print("Failed to add 12 to the dataqueue")
end
print("The dataqueue contains:")
while dataqueue.count > 0 do
print(dataqueue.next())
end
Clear the data queue.
Each line adds one item to the data queue.
Output:
The dataqueue contains:
1.01
1.01
1.01
