Returns information about the current state of a queue, such as the number of elements currently in the queue.
Reference to a queue. Use Obtain Queue to obtain a queue reference.
Error conditions that occur before this node runs.
This node runs normally even if an error occurred before this node runs. Otherwise, the node responds to this input according to standard error behavior.
The name of the queue.
Reference to the queue unchanged.
The number of Dequeue Element or Preview Queue Element nodes currently waiting to remove an element from the queue.
Refer to the Dequeue Element and Preview Queue Element nodes for more information.
The number of nodes currently waiting to insert an element in the queue. Use the Enqueue Element or Enqueue Element at Opposite End nodes to insert an element in the queue. If the max queue size is -1, # pending insert this output is 0.
Error information. The node produces this output according to standard error behavior.
Current number of elements in the queue.
All the elements currently in the queue. If return elements? is FALSE, this array is empty. This data type changes to match the subtype of queue.
