Class: wnet.FIFOQueue Namespace: wnet
Determine if FIFO queue is full
Since R2026a
status = isFull(queueObj)
status = isFull(queueObj) determines if the first-in first-out (FIFO) queue queueObj, is full, and returns the status status.
status
queueObj
example
expand all
Create a FIFO queue for 1000 packets.
queueObj = wnet.FIFOQueue(MaxSize=1000);
Create a sample packet and specify the packet size.
packet = [255;255]; packetSize = numel(packet);
Add the packet to the tail of the queue.
isQueued = enqueue(queueObj,packet,packetSize);
Get the number of packets in the queue.
numPackets = queueObj.CurrentSize;
Get the number of packet bytes in the queue.
nBytes = queueObj.CurrentSizeBytes;
Check if the queue is full.
status = isFull(queueObj);
Retrieve the first packet from the head of the queue.
PeekedPacket = peek(queueObj);
Remove the packet from the head of the queue.
dequeuedPacket = dequeue(queueObj);
wnet.FIFOQueue
FIFO queue, specified as an object of class wnet.FIFOQueue class.
false
0
true
1
Status of the queue capacity, returned as a numeric or logical 0(false) or 1(true).
The status can be either of these values:
0— This indicates that the queue is not full. It can be an empty or partially full queue.
1— This indicates that the queue is full and has reached its maximum capacity.
