@Beta @GwtIncompatible("java.util.ArrayDeque") @Deprecated(since="2022-12-01") public final class EvictingQueue<E> extends ForwardingQueue<E>
Deprecated.The Google Guava Core Libraries are deprecated and will not be part of the AEM SDK after April 2023A non-blocking queue which automatically evicts elements from the head of the queue when attempting to add new elements onto the queue and it is full.An evicting queue must be configured with a maximum size. Each time an element is added to a full queue, the queue automatically removes its head element. This is different from conventional bounded queues, which either block or reject new elements when full.
This class is not thread-safe, and does not accept null elements.
