| org.xml.sax.DTDHandler
All known Subclasses: org.xml.sax.HandlerBase,
| DTDHandler | | public interface DTDHandler (Code) | | Receive notification of basic DTD-related events.
If a SAX application needs information about notations and
unparsed entities, then the application implements this
interface and registers an instance with the SAX parser using
the parser's setDTDHandler method. The parser uses the
instance to report notation and unparsed entity declarations to
the application.
The SAX parser may report these events in any order, regardless
of the order in which the notations and unparsed entities were
declared; however, all DTD events must be reported after the
document handler's startDocument event, and before the first
startElement event.
It is up to the application to store the information for
future use (perhaps in a hash table or object tree).
If the application encounters attributes of type "NOTATION",
"ENTITY", or "ENTITIES", it can use the information that it
obtained through this interface to find the entity and/or
notation corresponding with the attribute value.
The HandlerBase class provides a default implementation
of this interface, which simply ignores the events.

| Method Summary | |
| abstract public void | notationDecl(String name, String publicId, String systemId)
Receive notification of a notation declaration event. | | abstract public void | unparsedEntityDecl(String name, String publicId, String systemId, String notationName)
Receive notification of an unparsed entity declaration event.
Note that the notation name corresponds to a notation
reported by the notationDecl() event. |
| notationDecl | | abstract public void notationDecl(String name, String publicId, String systemId) throws SAXException(Code) | | Receive notification of a notation declaration event.
It is up to the application to record the notation for later
reference, if necessary.
If a system identifier is present, and it is a URL, the SAX
parser must resolve it fully before passing it to the
application.
Parameters:
name - The notation name.
Parameters:
publicId - The notation's public identifier, or null ifnone was given.
Parameters:
systemId - The notation's system identifier, or null ifnone was given.
exception:
org.xml.sax.SAXException - Any SAX exception, possiblywrapping another exception.

| unparsedEntityDecl | | abstract public void unparsedEntityDecl(String name, String publicId, String systemId, String notationName) throws SAXException(Code) | | Receive notification of an unparsed entity declaration event.
Note that the notation name corresponds to a notation
reported by the notationDecl() event. It is up to the
application to record the entity for later reference, if
necessary.
If the system identifier is a URL, the parser must resolve it
fully before passing it to the application.
exception:
org.xml.sax.SAXException - Any SAX exception, possiblywrapping another exception.
Parameters:
name - The unparsed entity's name.
Parameters:
publicId - The entity's public identifier, or null if nonewas given.
Parameters:
systemId - The entity's system identifier (it must alwayshave one).
Parameters:
notation - name The name of the associated notation.
