Methods

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.

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

newFactory

public static XMLEventFactory 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 XMLEventFactory implementation class to load:

  • Use the javax.xml.stream.XMLEventFactory system property.

  • Use the configuration file "stax.properties". The file is in standard Properties format and typically located in the conf directory of the Java installation. It contains the fully qualified name of the implementation class with the key being the system property defined above.

    The stax.properties file is read only once by the implementation and its values are then cached for future use. If the file does not exist when the first attempt is made to read from it, no further attempts are made to check for its existence. It is not possible to change the value of any property in stax.properties after it has been read for the first time.

    Use the jaxp configuration file "jaxp.properties". The file is in the same format as stax.properties and will only be read if stax.properties does not exist.

  • Use the service-provider loading facility, defined by the ServiceLoader class, to attempt to locate and load an implementation of the service using the default loading mechanism: 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, the system-default implementation is returned.

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

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 configuration file "stax.properties". The file is in standard Properties format and typically located in the conf directory of the Java installation. It contains the fully qualified name of the implementation class with the key being the system property defined above.

    The stax.properties file is read only once by the implementation and its values are then cached for future use. If the file does not exist when the first attempt is made to read from it, no further attempts are made to check for its existence. It is not possible to change the value of any property in stax.properties after it has been read for the first time.

    Use the jaxp configuration file "jaxp.properties". The file is in the same format as stax.properties and will only be read if stax.properties does not exist.

  • 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.
