Interface XmlReader

All Superinterfaces:

RowSetReader

public interface XmlReader
extends RowSetReader

A specialized interface that facilitates an extension of the SyncProvider abstract class for XML orientated synchronization providers.

SyncProvider implementations that supply XML data reader capabilities such as output XML stream capabilities can implement this interface to provide standard XmlReader objects to WebRowSet implementations.

An XmlReader object is registered as the XML reader for a WebRowSet by being assigned to the rowset's xmlReader field. When the WebRowSet object's readXml method is invoked, it in turn invokes its XML reader's readXML method.

Method Summary

Throws:

SQLException - if a database access error occurs or this XmlReader object is not the reader for the given rowset

Parameters:

caller - the WebRowSet object to be parsed, whose xmlReader field must contain a reference to this XmlReader object

reader - the java.io.Reader object from which caller will be read
