AbstractSVGDocumentHandler

public AbstractSVGDocumentHandler(IFContext context)

Method Details

getMainNamespace

protected String getMainNamespace()

Returns the main namespace used for generated XML content.

Specified by:

getMainNamespace in class AbstractXMLWritingIFDocumentHandler

Returns:

the main namespace

getFontInfo

public FontInfo getFontInfo()

Returns the font set to work with.

Specified by:

getFontInfo in interface IFDocumentHandler

Returns:

the font info object

setFontInfo

public void setFontInfo(FontInfo fontInfo)

Sets the font set to work with.

Specified by:

setFontInfo in interface IFDocumentHandler

Parameters:

fontInfo - the font info object

setDefaultFontInfo

public void setDefaultFontInfo(FontInfo fontInfo)

Sets the default font set (with no custom configuration).

Specified by:

setDefaultFontInfo in interface IFDocumentHandler

Parameters:

fontInfo - the font info object to populate

getConfigurator

public IFDocumentHandlerConfigurator getConfigurator()

Returns the configurator for this document handler, if any.

Specified by:

getConfigurator in interface IFDocumentHandler

Returns:

the configurator or null if there's no configurator

startDocumentHeader

public void startDocumentHeader()
                         throws IFException

Indicates the start of the document header. This method is called right after the IFDocumentHandler.startDocument() method. Extensions sent to this painter between IFDocumentHandler.startDocumentHeader() and IFDocumentHandler.endDocumentHeader() apply to the document as a whole (like document metadata).

Specified by:

startDocumentHeader in interface IFDocumentHandler

Overrides:

startDocumentHeader in class AbstractIFDocumentHandler

Throws:

IFException - if an error occurs while handling this event

endDocumentHeader

public void endDocumentHeader()
                       throws IFException

Indicates the end of the document header. This method is called before the first page sequence.

Specified by:

endDocumentHeader in interface IFDocumentHandler

Overrides:

endDocumentHeader in class AbstractIFDocumentHandler

Throws:

IFException - if an error occurs while handling this event

handleExtensionObject

public void handleExtensionObject(Object extension)
                           throws IFException

Handles an extension object. This can be a DOM document or any arbitrary object. If an implementation doesn't know how to handle a particular extension it is simply ignored.

Specified by:

handleExtensionObject in interface IFDocumentHandler

Parameters:

extension - the extension object

Throws:

IFException - if an error occurs while handling this event
