Class SAXDriver

      com.icl.saxon.aelfred.SAXDriver

All Implemented Interfaces:
  org.xml.sax.AttributeList, org.xml.sax.Attributes, org.xml.sax.Locator, org.xml.sax.Parser, org.xml.sax.XMLReader

public class SAXDriver
extends java.lang.Object
implements org.xml.sax.Locator, org.xml.sax.Attributes, org.xml.sax.XMLReader, org.xml.sax.Parser, org.xml.sax.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(java.util.Locale locale)
                   throws org.xml.sax.SAXException

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

  Specified by:
    `setLocale` in interface `org.xml.sax.Parser`
  Parameters:
    `locale` - The locale for which diagnostics will be generated
  Throws:
    `org.xml.sax.SAXException`

### getEntityResolver

    public org.xml.sax.EntityResolver getEntityResolver()

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

  Specified by:
    `getEntityResolver` in interface `org.xml.sax.XMLReader`

### setEntityResolver

    public void setEntityResolver(org.xml.sax.EntityResolver resolver)

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

  Specified by:
    `setEntityResolver` in interface `org.xml.sax.XMLReader`

### getDTDHandler

    public org.xml.sax.DTDHandler getDTDHandler()

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

  Specified by:
    `getDTDHandler` in interface `org.xml.sax.XMLReader`

### setDTDHandler

    public void setDTDHandler(org.xml.sax.DTDHandler handler)

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

  Specified by:
    `setDTDHandler` in interface `org.xml.sax.XMLReader`
  Parameters:
    `handler` - The object to receive DTD events.

### setDocumentHandler

    public void setDocumentHandler(org.xml.sax.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 `org.xml.sax.Parser`
  Parameters:
    `handler` - The object to receive document events.

### getContentHandler

    public org.xml.sax.ContentHandler getContentHandler()

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

  Specified by:
    `getContentHandler` in interface `org.xml.sax.XMLReader`

### setContentHandler

    public void setContentHandler(org.xml.sax.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 `org.xml.sax.XMLReader`

### setErrorHandler

    public void setErrorHandler(org.xml.sax.ErrorHandler handler)

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

  Specified by:
    `setErrorHandler` in interface `org.xml.sax.XMLReader`
  Parameters:
    `handler` - The object to receive error events.

### getErrorHandler

    public org.xml.sax.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 `org.xml.sax.XMLReader`

### parse

    public void parse(org.xml.sax.InputSource source)
               throws org.xml.sax.SAXException,
                      java.io.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 `org.xml.sax.XMLReader`
  Parameters:
    `source` - The XML input source. Don't set 'encoding' unless you know for a fact that it's correct.
  Throws:
    `org.xml.sax.SAXException` - The handlers may throw any SAXException, and the parser normally throws SAXParseException objects.
    `java.io.IOException` - IOExceptions are normally through through the parser if there are problems reading the source document.
