Constructor Details

XMLEventFactory

protected XMLEventFactory()

Protected constructor to prevent instantiation. Use newFactory() instead.

Method Details

newDefaultFactory

public static XMLEventFactory newDefaultFactory()

Creates a new instance of the XMLEventFactory builtin system-default implementation.

Returns:: A new instance of the XMLEventFactory builtin system-default implementation.
Since:: 9

newInstance

public static XMLEventFactory newInstance() throws FactoryConfigurationError

Creates a new instance of the factory in exactly the same manner as the newFactory() method.

Returns:: an instance of the XMLEventFactory
Throws:: FactoryConfigurationError - if an instance of this factory cannot be loaded

newFactory

public static XMLEventFactory newFactory() throws FactoryConfigurationError

Creates a new instance of the factory. This method uses the JAXP Lookup Mechanism to determine the XMLEventFactory implementation class to load.

Once an application has obtained a reference to a XMLEventFactory, it can use the factory to configure and obtain stream instances.

Returns:: an instance of the XMLEventFactory
Throws:: FactoryConfigurationError - in case of service configuration error or if the implementation is not available or cannot be instantiated.

newInstance

@Deprecated(since="1.7") public static XMLEventFactory newInstance(String factoryId, ClassLoader classLoader) throws FactoryConfigurationError

Deprecated.

This method has been deprecated to maintain API consistency. All newInstance methods have been replaced with corresponding newFactory methods. The replacement newFactory(java.lang.String, java.lang.ClassLoader) method defines no changes in behavior.

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 - if an instance of this factory cannot be loaded

newFactory

public static XMLEventFactory 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.

This method uses the following ordered lookup procedure to determine the XMLEventFactory implementation class to load:

Use the value of the system property identified by factoryId.
Use the value of the property factoryId set in the configuration file, jaxp.properties by default. If the file exists and the property factoryId is specified in the file, its value will be used as the implementation class.
If factoryId is "javax.xml.stream.XMLEventFactory", use the service-provider loading facility, defined by the ServiceLoader class, to attempt to locate and load an implementation of the service using the specified ClassLoader. If classLoader is null, the default loading mechanism will apply: That is, the service-provider loading facility will use the current thread's context class loader to attempt to load the service. If the context class loader is null, the system class loader will be used.
Otherwise, throws a FactoryConfigurationError.

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.

API Note:: The parameter factoryId defined here is inconsistent with that of other JAXP factories where the first parameter is fully qualified factory class name that provides implementation 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 - in case of service configuration error or if the implementation is not available or cannot be instantiated.

setLocation
