This is the problem:
I have two agent populations; "Blue rectangles" and "Red rectangles". Both of these agents go into the same queue. However it is a little hard to know how many red and blue rectangles are in the queue at an arbitraty time T.
Are there some functions/techniques to fetch this?
Would like to e.g. print in the console: "There are N blue rectangles and M red rectangles in the queue."
Sure, you can loop across all agents in your queue and check each by its agent type (assuming that blue and red agents are actually different agent types):
for (int i=0; i<myQueue.size(); i++) {
if (myQueue.get(i) instanceof AgentTypeBlue) {
// do whatever you want to count blue agents
} else if (myQueue.get(i) instanceof AgentTypeRed) {
// do whatever you want to count red agents
}
}
Alternatively, just use the Queues "on enter" and "on exit" code boxes to count whenever a blue or red agent enters & leaves (using a variable countRed/countBlue`) as below:
