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
