类 ContentionStrategy

java.lang.Object

io.shardingsphere.orchestration.reg.newzk.client.zookeeper.strategy.BaseStrategy

io.shardingsphere.orchestration.reg.newzk.client.zookeeper.strategy.UsualStrategy

io.shardingsphere.orchestration.reg.newzk.client.zookeeper.strategy.ContentionStrategy

所有已实现的接口:

IAction, IExecStrategy, IGroupAction

直接已知子类:

TransactionContendStrategy

public class ContentionStrategy
extends UsualStrategy

The contention strategy is effective only when all the clients of the node which be competitive are using contention strategy.
