XMLEventFactory

New instances of the abstract class

XMLEventFactory

are created by calling the

newInstance()

method on the class. The static method

XMLEventFac-

tory.newInstance()

is then used to create a new factory instance. This factory

references the

javax.xml.stream.XMLEventFactory

property to instantiate the

factory. The algorithm used to obtain the instance is the same as for

XMLInput-

Factory

and

XMLOutputFactory

but references the

javax.xml.stream.XMLEv-

entFactory

system property.

There are no default properties for

XMLEventFactory

Resources, Namespaces, and Errors

The StAX specification handles resource allocation, attributes and namespace,
and errors and exceptions as described below.

Resource Resolution

The

XMLResolver

interface provides a means to set the method that resolves

resources during XML processing. An application sets the interface on

XMLIn-

putFactory

, which then sets the interface on all processors created by that fac-

tory instance.

Attributes and Namespaces

Attributes are reported by a StAX processor using lookup methods and strings in
the cursor interface and

Attribute

and

Namespace

events in the iterator inter-

face. Note here that namespaces are treated as attributes, although namespaces
are reported separately from attributes in both the cursor and iterator APIs. Note
also that namespace processing is optional for StAX processors. See the StAX
specification for complete information about namespace binding and optional
namespace processing.
