示例1: testRemainingCapacity

* remainingCapacity decreases on add, increases on remove
*/
public void testRemainingCapacity() {
int size = ThreadLocalRandom.current().nextInt(1, SIZE);

示例2: remainingCapacity
import java.util.concurrent.BlockingQueue; //导入方法依赖的package包/类

* Returns maximum remaining capacity. This does not reflect how much you can
* ideally fit in this FairCallQueue, as that would depend on the scheduler's
* decisions.
