Class EventToStaxBridge

java.lang.Object

net.sf.saxon.evpull.EventToStaxBridge

All Implemented Interfaces:

XMLStreamConstants, XMLStreamReader

public class EventToStaxBridge
extends Object
implements XMLStreamReader

This class bridges EventIterator events to XMLStreamReader (Stax) events. That is, it acts as an XMLStreamReader, fetching the underlying data from an EventIterator.

An EventIterator may provide access to any XDM sequence, whereas an XMLStreamReader always reads a document. The conversion of a sequence to a document follows the rules for "normalizing" a sequence in the Serialization specification: for example, atomic values are converted into text nodes, with adjacent atomic values being space-separated.

Constructor Detail

EventToStaxBridge

public EventToStaxBridge(EventIterator provider,
                 PipelineConfiguration pipe)

Create a EventToStaxBridge instance, which wraps a Saxon EventIterator as a Stax XMLStreamReader

Parameters:

provider - the Saxon EventIterator from which the events will be read. This must return a fully decomposed event stream, that is, document and element nodes must be presented as separate events for the start, content, and end.

pipe - the PipelineConfiguration
