Syntax
int
getQueueSize()
See also
addEvent
,
getMaxQueueSize
Returns
The integer number of messages in the gateway message queue that are waiting to be delivered to
CFCs.
Usage
You can use this method and the
getMaxQueueSize
method to control the rate of event queuing
and to help diagnose any throughput problems in your gateways.
Example
The following example logs the queue size, maximum queue size, and other information if a
gatewayService.addEvent
method fails to queue a message for delivery to a listener CFC. (It
uses an internal method to construct the error message string.)
boolean sent = gatewayService.addEvent(cfmsg);
if (!sent)
{
logger.error(RB.getString(this, "IMGateway.cantAddToQueue",
gatewayType, gatewayID, ((path != null) ? path : "default"),
Integer.ToString(gatewayService.getQueueSize()),
Integer.ToString(gatewayService.getMaxQueueSize())));
}
