Returns the element at the front of the queue without removing the element from the queue.
Reference to a queue. Use Obtain Queue to obtain a queue reference.
The time, in milliseconds, that the node waits for an element to become available in the queue if the queue is empty.
If the node waits the specified amount of time and the queue remains empty, timed out? is True.
Default: -1—Specifies the node never times out.
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.
Reference to the queue unchanged.
The element at the front of the queue. This data type changes to match the subtype of queue.
A Boolean that indicates whether an element did not become available in the queue before the node timed out or if an error occurred.
|TRUE||An element did not become available before the node timed out. Also returns TRUE if an error occurred.|
|FALSE||An element did become available before the node timed out.|
Error information. The node produces this output according to standard error behavior.
