It provides an abstraction for managing the XML/Java binding 325N/A * information necessary to implement the JAXB binding framework operations: 325N/A * unmarshal, marshal and validate. 325N/A * <p>A client application normally obtains new instances of this class using 325N/A * one of these two styles for newInstance methods, although there are other 325N/A * specialized forms of the method available: 325N/A * <li>{@link #newInstance(String,ClassLoader) JAXBContext.newInstance( "com.acme.foo:com.acme.bar" )} <br/> 325N/A * The JAXBContext instance is initialized from a list of colon 325N/A * separated Java package names. Each java package contains 325N/A * JAXB mapped classes, schema-derived classes and/or user annotated 325N/A * classes. Additionally, the java package may contain JAXB package annotations 325N/A * that must be processed. (see JLS, Section 7.4.1 "Named Packages"). 325N/A * <li>{@link #newInstance(Class...) JAXBContext.newInstance( com.acme.foo.Foo.class )} <br/> 325N/A * The JAXBContext instance is intialized with class(es) 325N/A * passed as parameter(s) and classes that are statically reachable from 325N/A * these class(es). See {@link #newInstance(Class...)} for details. 325N/A * <i><B>SPEC REQUIREMENT:</B> the provider must supply an implementation 325N/A * class containing the following method signatures:</i> 325N/A * public static JAXBContext createContext( String contextPath, ClassLoader classLoader, Map<String,Object> properties ) throws JAXBException 325N/A * public static JAXBContext createContext( Class[] classes, Map<String,Object> properties ) throws JAXBException 325N/A * The following JAXB 1.0 requirement is only required for schema to 325N/A * each package containing schema derived classes. The property file must 325N/A * contain a property named <tt>javax.xml.bind.context.factory</tt> whose 325N/A * value is the name of the class that implements the <tt>createContext</tt> 325N/A * The class supplied by the provider does not have to be assignable to 325N/A * <tt>javax.xml.bind.JAXBContext</tt>, it simply has to provide a class that 325N/A * implements the <tt>createContext</tt> APIs.</i> 325N/A * In addition, the provider must call the 325N/A * {@link DatatypeConverter#setDatatypeConverter(DatatypeConverterInterface) 325N/A * DatatypeConverter.setDatatypeConverter} api prior to any client 325N/A * invocations of the marshal and unmarshal methods. This is necessary to 325N/A * configure the datatype converter that will be used during these operations.</i> 325N/A * <a name="Unmarshalling"></a> 325N/A * <h3>Unmarshalling</h3> 325N/A * The {@link Unmarshaller} class provides the client application the ability 325N/A * to convert XML data into a tree of Java content objects. 325N/A * The unmarshal method allows for 325N/A * any global XML element declared in the schema to be unmarshalled as 325N/A * the root of an instance document. 325N/A * Additionally, the unmarshal method allows for an unrecognized root element that 325N/A * has an xsi:type attribute's value that references a type definition declared in 325N/A * the schema to be unmarshalled as the root of an instance document. 325N/A * The <tt>JAXBContext</tt> object 325N/A * allows the merging of global elements and type definitions across a set of schemas (listed 325N/A * in the <tt>contextPath</tt>). Since each schema in the schema set can belong 325N/A * to distinct namespaces, the unification of schemas to an unmarshalling 325N/A * context should be namespace independent. This means that a client 325N/A * application is able to unmarshal XML documents that are instances of 325N/A * any of the schemas listed in the <tt>contextPath</tt>. For example: 325N/A * JAXBContext jc = JAXBContext.newInstance( "com.acme.foo:com.acme.bar" ); 325N/A * Unmarshaller u = jc.createUnmarshaller(); 325N/A * FooObject fooObj = (FooObject)u.unmarshal( new File( "foo.xml" ) ); // ok 325N/A * BarObject barObj = (BarObject)u.unmarshal( new File( "bar.xml" ) ); // ok 325N/A * BazObject bazObj = (BazObject)u.unmarshal( new File( "baz.xml" ) ); // error, "com.acme.baz" not in contextPath 325N/A * The client application may also generate Java content trees explicitly rather 325N/A * than unmarshalling existing XML data. For all JAXB-annotated value classes, 325N/A * an application can create content using constructors. 325N/A * creation of elements that are not bound to a JAXB-annotated 325N/A * class, an application needs to have access and knowledge about each of 325N/A * the schema derived <tt> ObjectFactory</tt> classes that exist in each of 325N/A * java packages contained in the <tt>contextPath</tt>. For each schema 325N/A * derived java class, there is a static factory method that produces objects 325N/A * of that type. For example, 325N/A * assume that after compiling a schema, you have a package <tt>com.acme.foo</tt> 325N/A * that contains a schema derived interface named <tt>PurchaseOrder</tt>. In 325N/A * order to create objects of that type, the client application would use the 325N/A * factory method like this: 325N/A * com.acme.foo.PurchaseOrder po = 325N/A * com.acme.foo.ObjectFactory.createPurchaseOrder(); 325N/A * Once the client application has an instance of the the schema derived object, 325N/A * it can use the mutator methods to set content on it. 325N/A * For more information on the generated <tt>ObjectFactory</tt> classes, see 325N/A * Section 4.2 <i>Java Package</i> of the specification. 325N/A * <i><B>SPEC REQUIREMENT:</B> the provider must generate a class in each 325N/A * package that contains all of the necessary object factory methods for that 325N/A * package named ObjectFactory as well as the static 325N/A * <tt>newInstance( javaContentInterface )</tt> method</i> 325N/A * The {@link Marshaller} class provides the client application the ability 325N/A * to convert a Java content tree back into XML data. There is no difference 325N/A * between marshalling a content tree that is created manually using the factory 325N/A * methods and marshalling a content tree that is the result an <tt>unmarshal 325N/A * </tt> operation. Clients can marshal a java content tree back to XML data 325N/A * to a <tt>java.io.OutputStream</tt> or a <tt>java.io.Writer</tt>. The 325N/A * marshalling process can alternatively produce SAX2 event streams to a 325N/A * registered <tt>ContentHandler</tt> or produce a DOM Node object. 325N/A * Client applications have control over the output encoding as well as 325N/A * whether or not to marshal the XML data as a complete document or 325N/A * Here is a simple example that unmarshals an XML document and then marshals 325N/A * JAXBContext jc = JAXBContext.newInstance( "com.acme.foo" ); 325N/A * Unmarshaller u = jc.createUnmarshaller(); 325N/A * FooObject fooObj = (FooObject)u.unmarshal( new File( "foo.xml" ) ); 325N/A * // marshal to System.out 325N/A * Marshaller m = jc.createMarshaller(); 325N/A * m.marshal( fooObj, System.out ); 325N/A * Validation has been changed significantly since JAXB 1.0. The {@link Validator} 325N/A * class has been deprecated and made optional. This means that you are advised 325N/A * not to use this class and, in fact, it may not even be available depending on 325N/A * your JAXB provider. JAXB 1.0 client applications that rely on <tt>Validator</tt> 325N/A * will still work properly when deployed with the JAXB 1.0 runtime system. 325N/A * In JAXB 2.0, the {@link Unmarshaller} has included convenince methods that expose 325N/A * the JAXP 1.3 {@link javax.xml.validation} framework. Please refer to the 325N/A * {@link Unmarshaller#setSchema(javax.xml.validation.Schema)} API for more 325N/A * <h3>JAXB Runtime Binding Framework Compatibility</h3> 325N/A * The following JAXB 1.0 restriction only applies to binding schema to 325N/A * Since this binding does not require a common runtime system, a JAXB 325N/A * client application must not attempt to mix runtime objects (<tt>JAXBContext, 325N/A * Marshaller</tt>, etc. ) from different providers. This does not 325N/A * mean that the client application isn't portable, it simply means that a 325N/A * client has to use a runtime system provided by the same provider that was 325N/A * used to compile the schema. 325N/A * <h3>Discovery of JAXB implementation</h3> 325N/A * When one of the <tt>newInstance</tt> methods is called, a JAXB implementation is discovered 325N/A * by the following steps. 325N/A * For each package/class explicitly passed in to the {@link #newInstance} method, in the order they are specified, 325N/A * <tt>jaxb.properties</tt> file is looked up in its package, by using the associated classloader — 325N/A * this is {@link Class#getClassLoader() the owner class loader} for a {@link Class} argument, and for a package 325N/A * the speified {@link ClassLoader}. 325N/A * If such a file is discovered, it is {@link Properties#load(InputStream) loaded} as a property file, and 325N/A * the value of the {@link #JAXB_CONTEXT_FACTORY} key will be assumed to be the provider factory class. 325N/A * This class is then loaded by the associated classloader discussed above. 325N/A * This phase of the look up allows some packages to force the use of a certain JAXB implementation. 325N/A * (For example, perhaps the schema compiler has generated some vendor extension in the code.) 325N/A * If the system property {@link #JAXB_CONTEXT_FACTORY} exists, then its value is assumed to be the provider 325N/A * factory class. This phase of the look up enables per-JVM override of the JAXB implementation. 325N/A * This file follows the standard service descriptor convention, and if such a file exists, its content 325N/A * is assumed to be the provider factory class. This phase of the look up is for automatic discovery. 325N/A * It allows users to just put a JAXB implementation in a classpath and use it without any furhter configuration. 325N/A * Finally, if all the steps above fail, then the rest of the look up is unspecified. That said, 325N/A * the recommended behavior is to simply look for some hard-coded platform default JAXB implementation. 325N/A * This phase of the look up is so that JavaSE can have its own JAXB implementation as the last resort. 325N/A * Once the provider factory class is discovered, its 325N/A * <tt>public static JAXBContext createContext(String,ClassLoader,Map)</tt> method 325N/A * (see {@link #newInstance(String, ClassLoader, Map)} for the parameter semantics.) 325N/A * or <tt>public static JAXBContext createContet(Class[],Map)</tt> method 325N/A * (see {@link #newInstance(Class[], Map)} for the parameter semantics) are invoked 325N/A * to create a {@link JAXBContext}. 325N/A * @author <ul><li>Ryan Shoemaker, Sun Microsystems, Inc.</li><li>Kohsuke Kawaguchi, Sun Microsystems, Inc.</li><li>Joe Fialli, Sun Microsystems, Inc.</li></ul> 325N/A * @see S 7.4.1 "Named Packages" in Java Language Specification</a> 325N/A * The name of the property that contains the name of the class capable 325N/A * of creating new <tt>JAXBContext</tt> objects. 325N/A * Obtain a new instance of a <tt>JAXBContext</tt> class. 325N/A * This is a convenience method to invoke the 325N/A * {@link #newInstance(String,ClassLoader)} method with 325N/A * the context class loader of the current thread. 325N/A * @throws JAXBException if an error was encountered while creating the 325N/A * <tt>JAXBContext</tt> such as 325N/A * <li>failure to locate either ObjectFactory.class or jaxb.index in the packages</li> 325N/A * <li>an ambiguity among global elements contained in the contextPath</li> 325N/A * <li>failure to locate a value for the context factory provider property</li> 325N/A * <li>mixing schema derived packages from different providers on the same contextPath</li> 325N/A //return newInstance( contextPath, JAXBContext.class.getClassLoader() ); 325N/A * Obtain a new instance of a <tt>JAXBContext</tt> class. 325N/A * The client application must supply a context path which is a list of 325N/A * colon (':', \u005Cu003A) separated java package names that contain 325N/A * schema-derived classes and/or fully qualified JAXB-annotated classes. 325N/A * code is registered with the JAXBContext by the 325N/A * ObjectFactory.class generated per package. 325N/A * Alternatively than being listed in the context path, programmer 325N/A * annotated JAXB mapped classes can be listed in a 325N/A * <tt>jaxb.index</tt> resource file, format described below. 325N/A * Note that a java package can contain both schema-derived classes and 325N/A * user annotated JAXB classes. Additionally, the java package may 325N/A * contain JAXB package annotations that must be processed. (see JLS, 325N/A * Section 7.4.1 "Named Packages"). 325N/A * Every package listed on the contextPath must meet <b>one or both</b> of the 325N/A * following conditions otherwise a <tt>JAXBException</tt> will be thrown: 325N/A * <li>it must contain ObjectFactory.class</li> 325N/A * <li>it must contain jaxb.index</li> 325N/A * <b>Format for jaxb.index</b> 325N/A * The file contains a newline-separated list of class names. 325N/A * Space and tab characters, as well as blank 325N/A * lines, are ignored.

Classes that 325N/A * are reachable, as defined in {@link #newInstance(Class...)}, from the 325N/A * listed classes are also registered with JAXBContext. 325N/A * Constraints on class name occuring in a <tt>jaxb.index</tt> file are: 325N/A * <li>Must not end with ".class".</li> 325N/A * <li>Class names are resolved relative to package containing 325N/A * <tt>jaxb.index</tt> file.
