impl

Both are interfaces , with implementation classes within the sub-directory called impl .

这两个文件都是接口，类的实现在子目录impl下。

Create a directory impl under the application directory sample_spl .

在应用程序目录samplespl下创建目录impl。

Create two sub-directories under impl : include and lib .

在impl目录下创建两个子目录：include和lib。

New files are generated in the package services . impl , which you will use in the Java component in SCAModule .

新文件即在services.impl包中生成，这些文件将用于SCAModule中的Java组件。

Now you will copy the relevant files into the impl sub-directory under the application directory sample_spl to make the application self-contained .

现在，您将相关文件复制到应用程序目录samplespl下的impl子目录中，使应用程序成为自含应用程序。

Implementation class name : The name of the generated implementation file is based on the name of the original user-defined interface , with " Impl " appended at the end of the name .

实现类名称：生成的实现文件的名称以初始的用户定义接口的名称为基础，在名称后面加上“Impl”。

The addTiming () method first renames the existing method by appending " $ impl " to the end of the name , then creates a copy of the method using the original name .

addTiming（）方法首先通过在名字后面附加“$impl”重命名现有的方法，接着用原来的方法名创建该方法的一个拷贝。

One implementation ( in package org . apache . axiom . om . impl . dom ) is dual-headed , supporting both AXIOM and DOM interfaces with the same implementation classes .

其中一种实现（在org.apache.axiom.om.impl.dom包中）是双重功能的，使用相同的实现类同时支持AXIOM和DOM接口。
