java.lang.Objectorg.apache.axiom.om.util.StAXUtils
public class StAXUtils
Utility class containing StAX related methods.
This class defines a set of methods to get XMLStreamReader
and XMLStreamWriter
instances. This class caches the corresponding factories (XMLInputFactory
and XMLOutputFactory
objects) by classloader (default) or as singletons.
The behavior can be changed using setFactoryPerClassLoader(boolean)
.
Default properties for these factories can be specified using XMLInputFactory.properties and XMLOutputFactory.properties files. When a new factory is instantiated, this class will attempt to load the corresponding file using the context classloader. This class supports properties with boolean, integer and string values. Both standard StAX properties and implementation specific properties can be specified. This feature should be used with care since changing some properties to non default values will break Axiom. Good candidates for XMLInputFactory.properties are:
Good candidates for XMLOutputFactory.properties are:
