javax.transaction.xa Interface Xid
public interface Xid
Xid 接口是 X/Open 事务标识符 XID 结构的 Java 映射。此接口指定三种存取方法，以获取全局事务的格式 ID、全局事务 ID 和分支限定符。Xid 接口供事务管理器和资源管理器使用。此接口对应用程序不可见。
The Xid interface is a Java mapping of the X/Open transaction identifier XID structure. This interface specifies three accessor methods to retrieve a global transaction's format ID, global transaction ID, and branch qualifier. The Xid interface is used by the transaction manager and the resource managers. This interface is not visible to the application programs.
