Package eu.bandm.tools.util.xml

Class NamespaceOracle

java.lang.Object

eu.bandm.tools.util.xml.ContentProxy

eu.bandm.tools.util.xml.NamespaceOracle

All Implemented Interfaces:

ContentHandler

public class NamespaceOracle
extends ContentProxy

Invents new prefices for new NSUris and inserts the prefix mapping events. ASSUME output is piped into a NamespaceEmbedder.
The SAX event stream reaching this api must adhere to the following criteria

• All names are by "uri" and "localname", --- the "qname" field is ignored.
• There are no startPrefixMapping(String, String) and endPrefixMapping(String) calls in the stream, but they will be added by this filter.

Cf. the SAX info at sax project api
