| /** |
| * The <code>XMLEncoder</code> class is a complementary alternative to |
| * the <code>ObjectOutputStream</code> and can used to generate |
| * a textual representation of a <em>JavaBean</em> in the same |
| * way that the <code>ObjectOutputStream</code> can |
| * be used to create binary representation of <code>Serializable</code> |
| * objects. For example, the following fragment can be used to create |
| * a textual representation the supplied <em>JavaBean</em> |
| * and all its properties: |
| * <pre> |
| * XMLEncoder e = new XMLEncoder( |
| * new BufferedOutputStream( |
| * new FileOutputStream("Test.xml"))); |
| * e.writeObject(new JButton("Hello, world")); |
| * e.close(); |
| * </pre> |
| * Despite the similarity of their APIs, the <code>XMLEncoder</code> |
| * class is exclusively designed for the purpose of archiving graphs |
| * of <em>JavaBean</em>s as textual representations of their public |
| * properties. Like Java source files, documents written this way |
| * have a natural immunity to changes in the implementations of the classes |
| * involved. The <code>ObjectOutputStream</code> continues to be recommended |
| * for interprocess communication and general purpose serialization. |
| * <p> |
| * The <code>XMLEncoder</code> class provides a default denotation for |
| * <em>JavaBean</em>s in which they are represented as XML documents |
| * complying with version 1.0 of the XML specification and the |
| * UTF-8 character encoding of the Unicode/ISO 10646 character set. |
| * The XML documents produced by the <code>XMLEncoder</code> class are: |
| * <ul> |
| * <li> |
| * <em>Portable and version resilient</em>: they have no dependencies |
| * on the private implementation of any class and so, like Java source |
| * files, they may be exchanged between environments which may have |
| * different versions of some of the classes and between VMs from |
| * different vendors. |
| * <li> |
| * <em>Structurally compact</em>: The <code>XMLEncoder</code> class |
| * uses a <em>redundancy elimination</em> algorithm internally so that the |
| * default values of a Bean's properties are not written to the stream. |
| * <li> |
| * <em>Fault tolerant</em>: Non-structural errors in the file, |
| * caused either by damage to the file or by API changes |
| * made to classes in an archive remain localized |
| * so that a reader can report the error and continue to load the parts |
| * of the document which were not affected by the error. |
| * </ul> |
| * <p> |
| * Below is an example of an XML archive containing |
| * some user interface components from the <em>swing</em> toolkit: |
| * <pre> |
| * <?xml version="1.0" encoding="UTF-8"?> |
| * <java version="1.0" class="java.beans.XMLDecoder"> |
| * <object class="javax.swing.JFrame"> |
| * <void property="name"> |
| * <string>frame1</string> |
| * </void> |
| * <void property="bounds"> |
| * <object class="java.awt.Rectangle"> |
| * <int>0</int> |
| * <int>0</int> |
| * <int>200</int> |
| * <int>200</int> |
| * </object> |
| * </void> |
| * <void property="contentPane"> |
| * <void method="add"> |
| * <object class="javax.swing.JButton"> |
| * <void property="label"> |
| * <string>Hello</string> |
| * </void> |
| * </object> |
| * </void> |
| * </void> |
| * <void property="visible"> |
| * <boolean>true</boolean> |
| * </void> |
| * </object> |
| * </java> |
| * </pre> |
| * The XML syntax uses the following conventions: |
| * <ul> |
| * <li> |
| * Each element represents a method call. |
| * <li> |
| * The "object" tag denotes an <em>expression</em> whose value is |
| * to be used as the argument to the enclosing element. |
| * <li> |
| * The "void" tag denotes a <em>statement</em> which will |
| * be executed, but whose result will not be used as an |
| * argument to the enclosing method. |
| * <li> |
| * Elements which contain elements use those elements as arguments, |
| * unless they have the tag: "void". |
| * <li> |
| * The name of the method is denoted by the "method" attribute. |
| * <li> |
| * XML's standard "id" and "idref" attributes are used to make |
| * references to previous expressions - so as to deal with |
| * circularities in the object graph. |
| * <li> |
| * The "class" attribute is used to specify the target of a static |
| * method or constructor explicitly; its value being the fully |
| * qualified name of the class. |
| * <li> |
| * Elements with the "void" tag are executed using |
| * the outer context as the target if no target is defined |
| * by a "class" attribute. |
| * <li> |
| * Java's String class is treated specially and is |
| * written <string>Hello, world</string> where |
| * the characters of the string are converted to bytes |
| * using the UTF-8 character encoding. |
| * </ul> |
| * <p> |
| * Although all object graphs may be written using just these three |
| * tags, the following definitions are included so that common |
| * data structures can be expressed more concisely: |
| * <p> |
| * <ul> |
| * <li> |
| * The default method name is "new". |
| * <li> |
| * A reference to a java class is written in the form |
| * <class>javax.swing.JButton</class>. |
| * <li> |
| * Instances of the wrapper classes for Java's primitive types are written |
| * using the name of the primitive type as the tag. For example, an |
| * instance of the <code>Integer</code> class could be written: |
| * <int>123</int>. Note that the <code>XMLEncoder</code> class |
| * uses Java's reflection package in which the conversion between |
| * Java's primitive types and their associated "wrapper classes" |
| * is handled internally. The API for the <code>XMLEncoder</code> class |
| * itself deals only with <code>Object</code>s. |
| * <li> |
| * In an element representing a nullary method whose name |
| * starts with "get", the "method" attribute is replaced |
| * with a "property" attribute whose value is given by removing |
| * the "get" prefix and decapitalizing the result. |
| * <li> |
| * In an element representing a monadic method whose name |
| * starts with "set", the "method" attribute is replaced |
| * with a "property" attribute whose value is given by removing |
| * the "set" prefix and decapitalizing the result. |
| * <li> |
| * In an element representing a method named "get" taking one |
| * integer argument, the "method" attribute is replaced |
| * with an "index" attribute whose value the value of the |
| * first argument. |
| * <li> |
| * In an element representing a method named "set" taking two arguments, |
| * the first of which is an integer, the "method" attribute is replaced |
| * with an "index" attribute whose value the value of the |
| * first argument. |
| * <li> |
| * A reference to an array is written using the "array" |
| * tag. The "class" and "length" attributes specify the |
| * sub-type of the array and its length respectively. |
| * </ul> |
