Class SiGMLResolver

java.lang.Object
  sigmlgen.SiGMLResolver

All Implemented Interfaces:

org.xml.sax.EntityResolver, CleanerEntityResolver

public class SiGMLResolver
extends java.lang.Object
implements CleanerEntityResolver

A SAX entity resolver for the standard SiGML DTDs, that is, for the SiGML DTD, the HamNoSysML (HML) DTD, and the SiGML-stream DTD. By default, these all resolve to local copies of the standard DTDs, but alternative local versions may be specified at construction time.

Constructor Summary

SiGMLResolver()
Constructs a resolver for the SiGML DTDs that uses the standard local copies.

SiGMLResolver(java.lang.String hmldtd, java.lang.String sigmldtd)
Constructs a resolver for the SiGML DTDs that uses the specified file names, if present, for the HML and SiGML DTDs; in either case a null argument implies use of the standard DTD file name.

Method Summary

org.xml.sax.InputSource

resolveEntity(java.lang.String publicId, java.lang.String systemId) Resolves the SAX entity with the given public and system IDs: if the given system ID is the URI of one of the SiGML DTDs, then a SAX input source for this resolver's version of that DTD will be returned, but in all other cases this method returns null.
