| **获取资源入口** | `acquire(int arg)` | `acquireShared(int arg)` |
| **释放资源入口** | `release(int arg)` | `releaseShared(int arg)` |

| **tryXxx 返回值** | `boolean`，`true` 表示获取/释放成功 | `int`（获取时），负数表示失败，0 表示成功但无剩余资源，正数表示成功且有剩余资源；`boolean`（释放时） |
| **唤醒后继节点** | 释放资源时唤醒一个后继节点 | 获取资源成功后，如果还有剩余资源，会继续唤醒后续节点（传播唤醒） |
| **Node 类型标识** | `Node.EXCLUSIVE`（`null`） | `Node.SHARED`（一个静态的 `Node` 实例） |
