MTFCOCA⁷⁵¹¹⁸ 基本例句 =Mechanical Time Fuse 机械定时引信¹⁰⁰ The tutorial ends with a presentation of the MTF launcher, which allows you to run the example. 指南结束于一个 MTF安装工具的表达,它使你能够运行例子。 ibm The MTF transformation engine then executes those rules to synchronize the target model files with the source model files. MTF转换引擎将随后执行这些规则来将目标模型文件与源模型文件同步。 ibm A relation in MTF also referred to as a mapping rule defines a type of mapping that will apply to instances of given model classes. 在 MTF中的一个关系也称为一个映射规则定义了一种可应用于给定模型类的实例的映射类型。 ibm An MTF transformation results in a set of mappings that relate objects among different models; an object unbound to any mapping is considered out of the scope of the transformation. 一个 MTF转换的结果是一组映射,它们把不同模型中的对象联系起来;一个与任何映射都无关的对象被认为是位于转换域外的。 ibm As you may have already guessed, the relations that drive the transformations play an important role in MTF. 正如你可能已经猜到的,驱动转换的关联在 MTF中起着重要作用。 ibm First, you'll get a brief overview of MTF what is it, what are the important use- cases, and so on. 首先,你将了解对 MTF的简要概述它是什么,有哪些重要的用例,等等。 ibm From a tooling perspective, MTF offers a low- cost approach for smoothly integrating tools based on EMF models. 从工具的角度看, MTF提供了基于 EMF模型的低成本、成功集成的工具。 ibm Open it with the MTF mapping rule editor.rdl is the default extension bound to the editor. 使用 MTF映射规则编辑器打开该文件. rdl是编辑器默认的文件扩展名。 ibm The configuration screen for the MTF task is presented in Figure10. MTF任务的配置画面如图10所示。 ibm The relation defined in Listing9 is another example of the multiple uses of relations in MTF. 列表9定义的关联是 MTF中关联多种使用的又一个例子。 ibm This example explains the basics of the RDL language, which should help you get started with MTF. 这个例子解释了 RDL语言的基础,这将帮助你开始学习 MTF。 ibm This file extension is associated with the MTF mapping rules editor. 此文件扩展名与 MTF映射规则编辑器关联。 ibm This is a good example of tool integration based on MTF. 这是基于 MTF的一个很好的工具集成的例子。 ibm This mechanism is called correspondence and allows MTF to traverse a whole model by applying all the correspondences reachable directly or transitively from the top-level relation. 这种机制称为通讯,它允许 MTF通过把从顶级关联开始的所有通讯变为可到达的直接或间接横跨一个完整模型。 ibm This section discusses how MTF can be used in a concrete case: a UML to Relational database RDB model transformation. 这一节讨论如何在一个具体用例中使用 MTF:一个 UML到关联数据库 RDB模型的转换。 ibm This step requires post- processing after MTF has completed its transformation, using the Modeler APIs. 此步骤要求在 MTF完成转换后使用 Modeler API进行后续处理。 ibm Using this model as input, you will be able to run an MTF task and generate the related relational schema. 使用这个模型作为输入,你将能够运行一个 MTF任务并产生相关的关联模型。 ibm MTF contributes to the Eclipse workbench by providing a mapping view that allows you to inspect the mappings generated by the transformation engine. MTF在 Eclipse工作环境中的作用是提供映射视图,通过它你可以检查由转换引擎产生的映射。 ibm MTF applies these concepts to EMF models. MTF把这些概念应用于 EMF模型。 ibm MTF implements some of the QVT concepts and is based on the EMF. MTF实现了 QVT的一些概念,并且是基于 EMF的。 ibm MTF is designed to perform transformations on EMF models, but it also provides a way to adapt non- EMF classes. MTF的设计是对 EMF模型进行转换,但是它也提供了改写非 EMF类的方法。 ibm MTF lets you define a transformation between models as a set of declarative rules also called relations, using the MTF relation definition language. 通过 MTF,可以使用 MTF关系定义语言将模型之间的转换作为一组声明规则也称为关系加以定义。 ibm MTF offers a declarative approach to model transformation. MTF为模型转换提供了一种声明的方式。 ibm MTF runs on Eclipse3.0 or higher, with the associated EMF level. MTF运行在 Eclipse3.0或更高版本上,配合相应的 EMF级别。 ibm MTF supports a flexible transformation model that can accept multiple models, relate multiple elements, and update multiple models. MTF支持一个灵活的转换模型,它可以接受多个模型,联系多个元素,并更新多个模型。 ibm MTF works only with EMF models, which you should be familiar with to use it successfully. MTF仅适用于 EMF模型,为了能成功使用,应该对其加以熟悉。 ibm MTF comes as a set of plug-ins that you can deploy in either Eclipse or the IBM Software Development Platform products. MTF的外在形式是一组你可以在 Eclipse或者 IBM软件开发平台产品上部署的插件。 ibm |
