Providing lock-based access to nodes in a concurrent linked list |
| 摘要 |
A method of providing lock-based access to nodes in a concurrent linked list includes providing a plurality of striped lock objects. Each striped lock object is configured to lock at least one of the nodes in the concurrent linked list. An index is computed based on a value stored in a first node to be accessed in the concurrent linked list. A first one of the striped lock objects is identified based on the computed index. The first striped lock object is acquired, thereby locking and providing protected access to the first node. |

1. A method utilizing at least a computing device for providing lock-based access to nodes in a concurrent linked list, comprising:
providing a plurality of striped lock objects, each striped lock object having a corresponding index and configured to lock at least one of the nodes in the concurrent linked list; identifying a hash code based on a value stored in a first node to be accessed in the concurrent linked list; computing an index based on the identified hash code and a total number of the plurality of striped lock objects; identifying a first one of the plurality of striped lock objects based on the computed index; and acquiring the first striped lock object, thereby locking and providing protected access to the first node. |
