dataqueue.clear()
This function clears the data queue.
Type TSP-Link accessible
Affected by Where saved Default value
Function
Yes
Usage
dataqueue.clear()
Details
This function forces all dataqueue.add() commands that are in progress to time out and deletes all
data from the data queue.
Example
MaxCount = dataqueue.CAPACITY
while dataqueue.count < MaxCount do
dataqueue.add(1)
end
print("There are " .. dataqueue.count
.. " items in the data queue")
dataqueue.clear()
print("There are " .. dataqueue.count
.. " items in the data queue")
This example fills the data queue and prints the
number of items in the queue. It then clears the
queue and prints the number of items again.
Output:
There are 128 items in the data
queue
There are 0 items in the data queue
