XMLInputFactory

protected XMLInputFactory()

Method Detail

newInstance

public static XMLInputFactory newInstance()
                                   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 XMLInputFactory implementation class to load: Use the javax.xml.stream.XMLInputFactory 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.XMLInputFactory in jars available to the runtime. Platform default XMLInputFactory instance. Once an application has obtained a reference to a XMLInputFactory it can use the factory to configure and obtain stream instances.

Throws:

FactoryConfigurationError - if an instance of this factory cannot be loaded

public static XMLInputFactory newInstance(String factoryId,
