当我遍历sprite列表并检查它们是否实现usesobjectpool时，由于类型擦除，我遇到了以下问题：

• 如果我尝试检查它的类型，我得到：

无法检查已擦除类型的示例：usesobjectpool

if(it is UsesObjectPool<Sprite>)
        {
            it.objectPool.releaseObject(it)
        }

如果我用通配符*来检查，它说：
必需参数nothing，找到sprite和usesobjectpool:

if(it is UsesObjectPool<*>)
            {
                it.objectPool.releaseObject(it)
            }

• 如果我将它转换为usesobjectpool，我会得到：

类型参数不在其范围内。应为：usesobjectpool找到：sprite

if(it is UsesObjectPool<*>)
            {
                (it as UsesObjectPool<Sprite>).objectPool.releaseObject(it)
            }

泛型类和接口：

interface UsesObjectPool<T> where T :UsesObjectPool<T>, T : Sprite
     {
         val objectPool: BaseObjectPool<T>
     }

abstract class BaseObjectPool<T> where T : UsesObjectPool<T>, T : Sprite
    {
        fun releaseObject(instance: T)
       {
          //Implementation
       }
    }
