Method Detail

registerReportHandler

public void registerReportHandler(ReportScopeHandler carteHandler)

Description copied from interface: ForeignNamespaceHandler

Registers a ReportScopeHandler to receive callbacks (events) from this ForeignNamespaceHandler.

Specified by:

registerReportHandler in interface ForeignNamespaceHandler

Parameters:

carteHandler - the handler

setTargetDocumentDeclaration

public void setTargetDocumentDeclaration(String dtdDecl)
                                  throws info.informatica.doc.DocumentFormatException

Description copied from interface: ForeignNamespaceHandler

Sets the document type declaration of the target document format.

Intended only for reports that have an XML format as destination.

Specified by:

setTargetDocumentDeclaration in interface ForeignNamespaceHandler

Parameters:

dtdDecl - the document type declaration.

Throws:

info.informatica.doc.DocumentFormatException - if the document type is not supported.

startElement

public void startElement(String uri,
                         String localName,

Overrides:

startElement in class DefaultHandler

Throws:

public void characters(char[] ch,
                       int start,
                       int length)
                throws SAXException

Overrides:

Throws:

SAXException

endElement

public void endElement(String uri,
                       String localName,
                       String qName)
                throws SAXException

Overrides:

endDocument in class DefaultHandler

Throws:

SAXException

flush

public void flush()
           throws SAXException

Description copied from interface: ForeignNamespaceHandler

Flushes the handler.

Handlers are required to merge as much templates as possible, to optimize the report. Small templates should be merged to form a larger one, and this merged template must be committed when this method is called. This is typically done when the end of the document, or a new report tag, is found.

When the handler is flushed, it should commit any pending work.

Specified by:

flush in interface ForeignNamespaceHandler

Throws:

SAXException - if any problem is found when flushing.

isInsideForeignElement

public boolean isInsideForeignElement()

Description copied from interface: ForeignNamespaceHandler

The parsing is considered to be inside a foreign element when it is not inside a Report element.

Specified by:

isInsideForeignElement in interface ForeignNamespaceHandler

Returns:

true or false depending on the current handler state.
