Method Detail

parse

public void parse(java.lang.String value)
           throws org.xml.sax.SAXException,
                  java.io.IOException

getFlexFromXML

public org.media.mn8.concepts.ElementConcept getFlexFromXML(org.media.mn8.concepts.StringConcept xmlDocument)

startDocument

public void startDocument()
                   throws org.xml.sax.SAXException
Description copied from class: org.xml.sax.helpers.DefaultHandler
Receive notification of the beginning of the document.

By default, do nothing. Application writers may override this method in a subclass to take specific actions at the beginning of a document (such as allocating the root node of a tree or creating an output file).

Specified by:
startDocument in interface org.xml.sax.ContentHandler

endDocument

public void endDocument()
                 throws org.xml.sax.SAXException
Description copied from class: org.xml.sax.helpers.DefaultHandler
Receive notification of the end of the document.

By default, do nothing. Application writers may override this method in a subclass to take specific actions at the end of a document (such as finalising a tree or closing an output file).

Specified by:
endDocument in interface org.xml.sax.ContentHandler

startElement

public void startElement(java.lang.String uri,
                         java.lang.String localname,
                         java.lang.String qname,
                         org.xml.sax.Attributes attributes)
                  throws org.xml.sax.SAXException
Description copied from class: org.xml.sax.helpers.DefaultHandler
Receive notification of the start of an element.

By default, do nothing. Application writers may override this method in a subclass to take specific actions at the start of each element (such as allocating a new tree node or writing output to a file).

Specified by:
startElement in interface org.xml.sax.ContentHandler

endElement

public void endElement(java.lang.String uri,
                       java.lang.String localname,
                       java.lang.String qname)
                throws org.xml.sax.SAXException
Description copied from class: org.xml.sax.helpers.DefaultHandler
Receive notification of the end of an element.

By default, do nothing. Application writers may override this method in a subclass to take specific actions at the end of each element (such as finalising a tree node or writing output to a file).

Specified by:
endElement in interface org.xml.sax.ContentHandler

characters

public void characters(char[] ch,
                       int start,
                       int length)
                throws org.xml.sax.SAXException
Description copied from class: org.xml.sax.helpers.DefaultHandler
Receive notification of character data inside an element.

By default, do nothing. Application writers may override this method to take specific actions for each chunk of character data (such as adding the data to a node or buffer, or printing it to a file).

Specified by:
characters in interface org.xml.sax.ContentHandler

ignorableWhitespace

public void ignorableWhitespace(char[] ch,
                                int start,
                                int length)
                         throws org.xml.sax.SAXException
Description copied from class: org.xml.sax.helpers.DefaultHandler
Receive notification of ignorable whitespace in element content.

By default, do nothing. Application writers may override this method to take specific actions for each chunk of ignorable whitespace (such as adding data to a node or buffer, or printing it to a file).

Specified by:
ignorableWhitespace in interface org.xml.sax.ContentHandler

processChar

public void processChar(java.lang.String val)

resolveEntity

public org.xml.sax.InputSource resolveEntity(java.lang.String publicId,
                                             java.lang.String systemId)
Description copied from interface: org.xml.sax.EntityResolver
Allow the application to resolve external entities.

The parser will call this method before opening any external entity except the top-level document entity. Such entities include the external DTD subset and external parameter entities referenced within the DTD (in either case, only if the parser reads external parameter entities), and external general entities referenced within the document element (if the parser reads external general entities). The application may request that the parser locate the entity itself, that it use an alternative URI, or that it use data provided by the application (as a character or byte input stream).

Application writers can use this method to redirect external system identifiers to secure and/or local URIs, to look up public identifiers in a catalogue, or to read an entity from a database or other input source (including, for example, a dialog box). Neither XML nor SAX specifies a preferred policy for using public or system IDs to resolve resources. However, SAX specifies how to interpret any InputSource returned by this method, and that if none is returned, then the system ID will be dereferenced as a URL.

If the system identifier is a URL, the SAX parser must resolve it fully before reporting it to the application.

Specified by:
resolveEntity in interface org.xml.sax.EntityResolver

appendString

void appendString(org.media.mn8.concepts.ElementConcept toElem,
                  java.lang.String value)
