## Uses of Interface
org.xml.sax.DTDHandler

Packages that use DTDHandler
javax.xml.transform.sax: This package implements SAX2-specific transformation APIs.
org.xml.sax: This package provides the core SAX APIs.
org.xml.sax.ext: This package contains interfaces to SAX2 facilities that conformant SAX drivers won't necessarily support.
org.xml.sax.helpers: This package contains "helper" classes, including support for bootstrapping SAX-based applications.

### Uses of DTDHandler in javax.xml.transform.sax

Subinterfaces of DTDHandler in javax.xml.transform.sax
`interface` `TransformerHandler` A TransformerHandler listens for SAX ContentHandler parse events and transforms them to a Result.

### Uses of DTDHandler in org.xml.sax

Classes in org.xml.sax that implement DTDHandler
`class` `HandlerBase` Deprecated. This class works with the deprecated `DocumentHandler` interface. It has been replaced by the SAX2 `DefaultHandler` class.

Methods in org.xml.sax that return DTDHandler
`DTDHandler` XMLReader.`getDTDHandler()` Return the current DTD handler.

Methods in org.xml.sax with parameters of type DTDHandler
`void` XMLReader.`setDTDHandler(DTDHandler handler)` Allow an application to register a DTD event handler.
`void` Parser.`setDTDHandler(DTDHandler handler)` Deprecated. Allow an application to register a DTD event handler.

### Uses of DTDHandler in org.xml.sax.ext

Classes in org.xml.sax.ext that implement DTDHandler
`class` `DefaultHandler2` This class extends the SAX2 base handler class to support the SAX2 `LexicalHandler`, `DeclHandler`, and `EntityResolver2` extensions.

### Uses of DTDHandler in org.xml.sax.helpers

Classes in org.xml.sax.helpers that implement DTDHandler
`class` `DefaultHandler` Default base class for SAX2 event handlers.
`class` `XMLFilterImpl` Base class for deriving an XML filter.

Methods in org.xml.sax.helpers that return DTDHandler
`DTDHandler` XMLFilterImpl.`getDTDHandler()` Get the current DTD event handler.
`DTDHandler` ParserAdapter.`getDTDHandler()` Return the current DTD handler.

Methods in org.xml.sax.helpers with parameters of type DTDHandler
`void` XMLReaderAdapter.`setDTDHandler(DTDHandler handler)` Register the DTD event handler.
`void` XMLFilterImpl.`setDTDHandler(DTDHandler handler)` Set the DTD event handler.
`void` ParserAdapter.`setDTDHandler(DTDHandler handler)` Set the DTD handler.
