Examples of org.apache.fop.apps.FOUserAgent

org.apache.fop.apps.FOUserAgent
This is the user agent for FOP. It is the entity through which you can interact with the XSL-FO processing and is used by the processing to obtain user configurable options.
Renderer specific extensions (that do not produce normal areas on the output) will be done like so:
The extension will create an area, custom if necessary
this area will be added to the user agent with a key
the renderer will know keys for particular extensions
eg. bookmarks will be held in a special hierarchical area representing the title and bookmark structure
These areas may contain resolvable areas that will be processed with other resolvable areas
