Methods

Modifier and Type	Method and Description
ContentHandlerFactory	getContentHandlerFactory() This method is overridden by extension elements and allows the extension element to return a ContentHandlerFactory.
ExtensionAttachment	getExtensionAttachment() This method is overridden by extension elements and allows the extension element to return a pass-through attachment which the parent formatting objects should simply carry with them but otherwise ignore.
void	notifyObjectBuilt(java.lang.Object obj) Notifies the listener when the object is fully built.

Constructor Detail

AbstractMetadataElement

public AbstractMetadataElement(FONode parent)

Main constructor.

Parameters:

parent - the parent formatting object

Method Detail

getContentHandlerFactory

public ContentHandlerFactory getContentHandlerFactory()

This method is overridden by extension elements and allows the extension element to return a ContentHandlerFactory. This factory can create ContentHandler implementations that handle foreign XML content by either building up a specific DOM, a Java object or something else.

Overrides:

getContentHandlerFactory in class FONode

Returns:

the ContentHandlerFactory or null if not applicable

getExtensionAttachment

public ExtensionAttachment getExtensionAttachment()

This method is overridden by extension elements and allows the extension element to return a pass-through attachment which the parent formatting objects should simply carry with them but otherwise ignore. This mechanism is used to pass non-standard information from the FO tree through to the layout engine and the renderers.

Overrides:

getExtensionAttachment in class FONode

Returns:

the extension attachment if one is created by the extension element, null otherwise.

notifyObjectBuilt

public void notifyObjectBuilt(java.lang.Object obj)

Notifies the listener when the object is fully built.

Specified by:

notifyObjectBuilt in interface ContentHandlerFactory.ObjectBuiltListener

Parameters:

obj - the newly built object
