All Implemented Interfaces:

IDContextProvider2, IVerifier, org.iso_relax.verifier.VerifierHandler, org.relaxng.datatype.ValidationContext, org.xml.sax.ContentHandler, org.xml.sax.DTDHandler

public class TypeDetector
extends Verifier

assign types to the incoming SAX2 events and reports them to the application handler through TypedContentHandler. This class "augment" infoset by adding type information. The application can receive augmented infoset by implementing TypedContentHandler.
