Intent

Event Queue is a good pattern if You have a limited accessibility resource (for example: Audio or Database), but You need to handle all the requests that want to use that. It puts all the requests in a queue and process them asynchronously. Gives the resource for the event when it is the next in the queue and in same time removes it from the queue.
