![]() However, instead of using java.io.ObjectInputStream, you use. Reading (unarchiving) a Java object from an XML archive is just as easy as reading it from a serialized object binary file. It is a simple program that deserializes an object from a binary file created by WriteQuark. ReadObj demonstrates the above algorithm. ObjectInputStream ois = new ObjectInputStream(fis) To read (deserialize) a Java object from a serialized object binary file, you use the following algorithm: // Create input streams.įileInputStream fis = new FileInputStream("foo.bin") It is a simple program that archives an instance of Quark to an XML archive. WriteQuarkXML demostrates the above algorithm. Here is the algorithm: // Create output stream.įileOutputStream fos = new FileOutputStream("foo.xml") However, instead of using java.io.ObjectOutputStream, you use. Writing (archiving) a Java object to an XML archive is just as easy as writing it to a serialized object binary file. It is a simple program that serializes an instance of Quark to a file. WriteQuark demonstrates the above algorithm. ObjectOutputStream oos = new ObjectOutputStream(fos) To write (serialize) a Java object to a file with the serialized object binary format, you use the following algorithm: // Create output streams.įileOutputStream fos = new FileOutputStream("foo.dat") ![]() (See “Resources” for links to more information on the Java XML archive format.) JFrame.xml is an example ofĪn archived GUI component. Bean.xml is an example of a simple, archived JavaBean. Java objects that are serialized using the long-term persistence classes are stored as Java XML archives. To try the example programs that accompany this article, you will need the following tools: This article illustrates how to use this new feature. Now, Java objects can be serialized as XML documents, a feature of the new long-term persistence API for JavaBeans. ![]() When performing Enterprise Architect-to-Enterprise Architect transfers, ensure that either XMI version 1.1 or XMI version 2.Until the release of Java 2 Standard Edition (J2SE) Version 1.4, Java objects could only be serialized to a proprietary, binary format.XMI 2.1 exported by Enterprise Architect 7.0 (or later) might not be correctly imported into earlier versions of Enterprise Architect.Importing a model from a MagicDraw MDZIP file.Importing a model from IBM Rational Rhapsody.Applying a UML Data Type Definition (DTD).Manually controlling a Package by linking it to an XMI file.Importing from XMI with support for XMI 2.1 (and earlier).Exporting a Package to XMI in XMI 2.1 (and earlier).Setting XML Options - XMI import, export and Package control all rely on saving and loading XML files you can set a number of options to streamline this process.Tasks you might perform in importing and exporting XMI include: Alternatively, use a merge file to merge the information in the XMI file with the contents of the Package. Please make sure you do not have important changes that you do not want to lose before importing from XML. When importing an XML file over an existing Package, by default all information in the current Package is deleted before the data is imported from the XML file. Packages can be exported from and imported into Enterprise Architect models, which greatly improves the flexibility and robustness of the models, helping Analysts and Modelers to externalize model elements in XMI for: Limited support for export to Rational Rose is provided using the Rose version of the XMI 1.1 specification, as implemented by Unisys for Rational products. ![]() With XMI, model details can be exchanged between different UML tools and other tools that are capable of using XMI. When importing or exporting to XMI 1.0, some loss of data occurs due to the limitations of XMI 1.0. XMI 1.1 provides support for UML 1.3, whereas XMI 2.x is used for UML 2.0 - 2.5.Įnterprise Architect does not fully support the older 1.0 specification. XMI and Enterprise ArchitectĮnterprise Architect uses XMI as a method of importing and exporting model specifications between different UML Packages, Enterprise Architect projects and other tools that support XMI. XML Metadata Interchange (XMI), defined by the OMG and based on XML, is an open standard file format that enables the interchange of model information between models and tools.
