Constructor Detail

StAXEventContentHandler

public StAXEventContentHandler()

Constructs a default instance with a default event factory. You must set the XMLEventConsumervia the setEventConsumer(XMLEventConsumer)method.

StAXEventContentHandler

public StAXEventContentHandler(XMLEventConsumer consumer)

Constructs an instance that writes events to the provided XMLEventConsumer. Events will be constructed from a default XMLEventFactory instance.

Parameters:

consumer - The XMLEventConsumerto which events will be written.

StAXEventContentHandler

public StAXEventContentHandler(XMLEventConsumer consumer,
                               XMLEventFactory factory)

Constructs an instance that writes events constructed with the provided XMLEventFactory to the provided XMLEventConsumer

Parameters:

consumer - The XMLEventConsumer to which events will be written.

factory - The XMLEventFactory used to construct events. If null, a default instance will be constructed.
