All Implemented Interfaces:

FeedReader

public class VespaXMLFeedReader
extends VespaXMLReader
implements FeedReader

XML parser for Vespa document XML. Parses an entire document "feed", which consists of a vespafeed element containing zero or more instances of documents, updates or removes. Standard usage is to create an Operation object and call read(Operation) until operation.getType() returns OperationType.INVALID. If you are looking to parse only a single document or update, use VespaXMLDocumentReader or VespaXMLUpdateReader respectively.
