javax.xml.rpc Interface Call

public interface Call


javax.xml.rpc.Call 接口提供对服务端点动态调用的支持。javax.xml.rpc.Service 接口充当创建 Call 实例的工厂。

创建了 Call 实例后，就可以使用各种设置方法和获取方法配置此 Call 实例。

version1.0
英文文档：

The javax.xml.rpc.Call interface provides support for the dynamic invocation of a service endpoint. The javax.xml.rpc.Service interface acts as a factory for the creation of Call instances.

Once a Call instance is created, various setter and getter methods may be used to configure this Call instance.
