org.web3d.x3d.jaxp.X3DSAVAdapter

All Implemented Interfaces:

ContentHandler, LexicalHandler

Direct Known Subclasses:

X3DSAVAdapterTolerant

public class X3DSAVAdapter
extends Object
implements LexicalHandler, ContentHandler

Interface adapter between XML input from a Simple API for XML (SAX) source to the Simple API for VRML Parsing (SAV) source used by the other parsers.

The implementation is a simplistic way for quickly getting XML content into the normal VRML input sources by adapting the SAX feeds to SAV feeds.

Constructor Details

X3DSAVAdapter

public X3DSAVAdapter()

Construct a default instance of this class.

Method Details

setLoadState

public void setLoadState(String worldURL,
 String fullURL,
 boolean overrideLex)

Set the loading state. Generally this is information that is gotten from the lexicalHandler. Seems XSLT transformation is keeping the lex handler to itself.

Parameters:

worldURL - the worldURL

fullURL - the full URL

overrideLex - Enable if lexicalHandling not working.

comment

public void comment(char[] ch,
 int start,
 int length)

Report an XML comment anywhere in the document.

Specified by:

comment in interface LexicalHandler

startDTD

public void startDTD(String name,
 String publicId,
 String systemId)
              throws SAXException

Report the start of DTD declarations, if any. There are two formal doctypes supported. The first type is the required type by the X3D specification:

   <!DOCTYPE X3D PUBLIC "-//Web3D//DTD X3D 3.0//EN"
    "http://www.web3d.org/specification/x3d/x3d-3_0.dtd">
 

The second type are the transitional DOCTYPEs used during development of the X3D specification.

   <!DOCTYPE X3D PUBLIC
    "http://www.web3D.org/TaskGroups/x3d/translation/x3d-compact.dtd"
    "/www.web3D.org/TaskGroups/x3d/translation/x3d-compact.dtd">
 

   <!DOCTYPE X3D PUBLIC
    "http://www.web3d.org/specifications/x3d-3.0.dtd"
    "/www.web3d.org/TaskGroups/x3d/translation/x3d-3.0.dtd">
 

It is advised that these forms are never used, it is for transitional content only. When this header is detected, a warning message is generated on the output, but parsing continues normally.

Parameters:

name - The DTD name string
