Class SAXDriver

java.lang.Object

com.icl.saxon.aelfred.SAXDriver

All Implemented Interfaces:

AttributeList, Attributes, Locator, Parser, XMLReader

public class SAXDriver
extends Object
implements Locator, Attributes, XMLReader, Parser, AttributeList

An enhanced SAX2 version of Microstar's Ælfred XML parser. The enhancements primarily relate to significant improvements in conformance to the XML specification, and SAX2 support. Performance has been improved. However, the Ælfred proprietary APIs are no longer public. See the package level documentation for more information.

Name	Notes
Features ... URL prefix is http://xml.org/sax/features/
(URL)/external-general-entities	Value is fixed at true
(URL)/external-parameter-entities	Value is fixed at true
(URL)/namespace-prefixes	Value defaults to false (but XML 1.0 names are always reported)
(URL)/namespaces	Value defaults to true
(URL)/string-interning	Value is fixed at true
(URL)/validation	Value is fixed at false
Handler Properties ... URL prefix is http://xml.org/sax/properties/
(URL)/declaration-handler	A declaration handler may be provided. Declaration of general entities is exposed, but not parameter entities; none of the entity names reported here will begin with "%".
(URL)/lexical-handler	A lexical handler may be provided. Entity boundaries and comments are not exposed; only CDATA sections and the start/end of the DTD (the internal subset is not detectible).

Note that the declaration handler doesn't suffice for showing all the logical structure of the DTD; it doesn't expose the name of the root element, or the values that are permitted in a NOTATIONS attribute. (The former is exposed as lexical data, and SAX2 beta doesn't expose the latter.)

Although support for several features and properties is "built in" to this parser, it support all others by storing the assigned values and returning them.

This parser currently implements the SAX1 Parser API, but it may not continue to do so in the future.

Constructor Detail

SAXDriver

public SAXDriver()

Constructs a SAX Parser.

Method Detail

setLocale

public void setLocale(Locale locale)
               throws SAXException

SAX1: Sets the locale used for diagnostics; currently, only locales using the English language are supported.

Specified by:

setLocale in interface Parser

Parameters:

locale - The locale for which diagnostics will be generated

Throws:

SAXException

getEntityResolver

public EntityResolver getEntityResolver()

SAX2: Returns the object used when resolving external entities during parsing (both general and parameter entities).

Specified by:

getEntityResolver in interface XMLReader

setEntityResolver

public void setEntityResolver(EntityResolver resolver)

SAX1, SAX2: Set the entity resolver for this parser.

Specified by:

setEntityResolver in interface Parser

Specified by:

setEntityResolver in interface XMLReader

Parameters:

handler - The object to receive entity events.

getDTDHandler

public DTDHandler getDTDHandler()

SAX2: Returns the object used to process declarations related to notations and unparsed entities.

Specified by:

getDTDHandler in interface XMLReader

setDTDHandler

public void setDTDHandler(DTDHandler handler)

SAX1, SAX2: Set the DTD handler for this parser.

Specified by:

setDTDHandler in interface Parser

Specified by:

setDTDHandler in interface XMLReader

Parameters:

handler - The object to receive DTD events.

setDocumentHandler

public void setDocumentHandler(DocumentHandler handler)

Deprecated. SAX2 programs should use the XMLReader interface and a ContentHandler.

SAX1: Set the document handler for this parser. If a content handler was set, this document handler will supplant it. The parser is set to report all XML 1.0 names rather than to filter out "xmlns" attributes (the "namespace-prefixes" feature is set to true).

Specified by:

setDocumentHandler in interface Parser

Parameters:

handler - The object to receive document events.

getContentHandler

public ContentHandler getContentHandler()

SAX2: Returns the object used to report the logical content of an XML document.

Specified by:

getContentHandler in interface XMLReader

setContentHandler

public void setContentHandler(ContentHandler handler)

SAX2: Assigns the object used to report the logical content of an XML document. If a document handler was set, this content handler will supplant it (but XML 1.0 style name reporting may remain enabled).

Specified by:

setContentHandler in interface XMLReader

setErrorHandler

public void setErrorHandler(ErrorHandler handler)

SAX1, SAX2: Set the error handler for this parser.

Specified by:

setErrorHandler in interface Parser

Specified by:

setErrorHandler in interface XMLReader

Parameters:

handler - The object to receive error events.

getErrorHandler

public ErrorHandler getErrorHandler()

SAX2: Returns the object used to receive callbacks for XML errors of all levels (fatal, nonfatal, warning); this is never null;

Specified by:

getErrorHandler in interface XMLReader

parse

public void parse(InputSource source)
           throws SAXException,
                  IOException

SAX1, SAX2: Auxiliary API to parse an XML document, used mostly when no URI is available. If you want anything useful to happen, you should set at least one type of handler.

Specified by:

parse in interface Parser

Specified by:

parse in interface XMLReader

Parameters:

source - The XML input source. Don't set 'encoding' unless you know for a fact that it's correct.

Throws:

SAXException - The handlers may throw any SAXException, and the parser normally throws SAXParseException objects.

IOException - IOExceptions are normally through through the parser if there are problems reading the source document.
