XMLOutputFactory (Java Platform SE 6) (original) (raw)

javax.xml.stream

Class XMLOutputFactory

java.lang.Object javax.xml.stream.XMLOutputFactory

public abstract class XMLOutputFactory

extends Object

Defines an abstract implementation of a factory for getting XMLEventWriters and XMLStreamWriters. The following table defines the standard properties of this specification. Each property varies in the level of support required by each implementation. The level of support required is described in the 'Required' column.

The following paragraphs describe the namespace and prefix repair algorithm:

The property can be set with the following code line:setProperty("javax.xml.stream.isRepairingNamespaces",new Boolean(true|false));

This property specifies that the writer default namespace prefix declarations. The default value is false.

If a writer isRepairingNamespaces it will create a namespace declaration on the current StartElement for any attribute that does not currently have a namespace declaration in scope. If the StartElement has a uri but no prefix specified a prefix will be assigned, if the prefix has not been declared in a parent of the current StartElement it will be declared on the current StartElement. If the defaultNamespace is bound and in scope and the default namespace matches the URI of the attribute or StartElement QName no prefix will be assigned.

If an element or attribute name has a prefix, but is not bound to any namespace URI, then the prefix will be removed during serialization.

If element and/or attribute names in the same start or empty-element tag are bound to different namespace URIs and are using the same prefix then the element or the first occurring attribute retains the original prefix and the following attributes have their prefixes replaced with a new prefix that is bound to the namespace URIs of those attributes.

If an element or attribute name uses a prefix that is bound to a different URI than that inherited from the namespace context of the parent of that element and there is no namespace declaration in the context of the current element then such a namespace declaration is added.

If an element or attribute name is bound to a prefix and there is a namespace declaration that binds that prefix to a different URI then that namespace declaration is either removed if the correct mapping is inherited from the parent context of that element, or changed to the namespace URI of the element or attribute using that prefix.

XMLOutputFactory

protected XMLOutputFactory()

newInstance

public static XMLOutputFactory newInstance() throws FactoryConfigurationError

Create a new instance of the factory.

Throws:

[FactoryConfigurationError](../../../javax/xml/stream/FactoryConfigurationError.html "class in javax.xml.stream") - if an instance of this factory cannot be loaded

newFactory

public static XMLOutputFactory newFactory() throws FactoryConfigurationError

Create a new instance of the factory. This static method creates a new factory instance. This method uses the following ordered lookup procedure to determine the XMLOutputFactory implementation class to load: Use the javax.xml.stream.XMLOutputFactory system property. Use the properties file "lib/stax.properties" in the JRE directory. This configuration file is in standard java.util.Properties format and contains the fully qualified name of the implementation class with the key being the system property defined above. Use the Services API (as detailed in the JAR specification), if available, to determine the classname. The Services API will look for a classname in the file META-INF/services/javax.xml.stream.XMLOutputFactory in jars available to the runtime. Platform default XMLOutputFactory instance. Once an application has obtained a reference to a XMLOutputFactory it can use the factory to configure and obtain stream instances. Note that this is a new method that replaces the deprecated newInstance() method. No changes in behavior are defined by this replacement method relative to the deprecated method.

Throws:

[FactoryConfigurationError](../../../javax/xml/stream/FactoryConfigurationError.html "class in javax.xml.stream") - if an instance of this factory cannot be loaded

newInstance

public static XMLInputFactory newInstance(String factoryId, ClassLoader classLoader) throws FactoryConfigurationError

Deprecated. This method has been deprecated because it returns an instance of XMLInputFactory, which is of the wrong class. Use the new method [newFactory(java.lang.String, java.lang.ClassLoader)](../../../javax/xml/stream/XMLOutputFactory.html#newFactory%28java.lang.String, java.lang.ClassLoader%29) instead.

Create a new instance of the factory.

Parameters:

factoryId - Name of the factory to find, same as a property name

classLoader - classLoader to use

Returns:

the factory implementation

Throws:

[FactoryConfigurationError](../../../javax/xml/stream/FactoryConfigurationError.html "class in javax.xml.stream") - if an instance of this factory cannot be loaded

newFactory

public static XMLOutputFactory newFactory(String factoryId, ClassLoader classLoader) throws FactoryConfigurationError

Create a new instance of the factory. If the classLoader argument is null, then the ContextClassLoader is used. Note that this is a new method that replaces the deprecated newInstance(String factoryId, ClassLoader classLoader) method. No changes in behavior are defined by this replacement method relative to the deprecated method.

Parameters:

factoryId - Name of the factory to find, same as a property name

classLoader - classLoader to use

Returns:

the factory implementation

Throws:

[FactoryConfigurationError](../../../javax/xml/stream/FactoryConfigurationError.html "class in javax.xml.stream") - if an instance of this factory cannot be loaded

createXMLStreamWriter
