Constructor Details

PageSequenceLayoutManager

public PageSequenceLayoutManager(AreaTreeHandler ath,
                                 PageSequence pseq)
Constructor
Parameters:
ath - the area tree handler object
pseq - fo:page-sequence to process

Method Details

activateLayout

public void activateLayout()
Activate the layout of this page sequence. PageViewports corresponding to each page generated by this page sequence will be created and sent to the AreaTreeModel for rendering.

addIDToPage

public void addIDToPage(String id)
Add an ID reference to the current page. When adding areas the area adds its ID reference. For the page layout manager it adds the id reference with the current page to the area tree.
Parameters:
id - the ID reference to add

addUnresolvedArea

public void addUnresolvedArea(String id,
                              Resolvable res)
Identify an unresolved area (one needing an idref to be resolved, e.g. the internal-destination of an fo:basic-link) for both the AreaTreeHandler and PageViewport object. The IDTracker keeps a document-wide list of idref's and the PV's needing them to be resolved. It uses this to send notifications to the PV's when an id has been resolved. The PageViewport keeps lists of id's needing resolving, along with the child areas (page-number-citation, basic-link, etc.) of the PV needing their resolution.
Parameters:
id - the ID reference to add
res - the resolvable object that needs resolving

associateLayoutManagerID

public boolean associateLayoutManagerID(String id)
Add an id reference of the layout manager in the AreaTreeHandler, if the id hasn't been resolved yet
Parameters:
id - the id to track
Returns:
a boolean indicating if the id has already been resolved TODO Maybe give this a better name

doForcePageCount

public void doForcePageCount(Numeric nextPageSeqInitialPageNumber)
Act upon the force-page-count trait, in relation to the initial-page-number trait of the following page-sequence.
Parameters:
nextPageSeqInitialPageNumber - initial-page-number trait of next page-sequence

finishPageSequence

public void finishPageSequence()
Finished the page-sequence and notifies everyone about it.

getCurrentPage

public Page getCurrentPage()
Provides access to the current page.
Overrides:
getCurrentPage in interface AbstractLayoutManager
Returns:
the current Page

getCurrentPageNum

protected int getCurrentPageNum()
Provides access to the current page number
Returns:
the current page number

getFirstPVWithID

public PageViewport getFirstPVWithID(String idref)
This returns the first PageViewport that contains an id trait matching the idref argument, or null if no such PV exists.
Parameters:
idref - the idref trait needing to be resolved
Returns:
the first PageViewport that contains the ID trait

getLastPVWithID

public PageViewport getLastPVWithID(String idref)
This returns the last PageViewport that contains an id trait matching the idref argument, or null if no such PV exists.
Parameters:
idref - the idref trait needing to be resolved
Returns:
the last PageViewport that contains the ID trait

getLayoutManagerMaker

public LayoutManagerMaker getLayoutManagerMaker()
Returns:
the LayoutManagerMaker object
See Also:
LayoutManager

getPSLM

public PageSequenceLayoutManager getPSLM()
Provides access to this object
Specified by:
getPSLM in interface LayoutManager
Overrides:
getPSLM in interface AbstractLayoutManager
Returns:
this PageSequenceLayoutManager instance

getPageProvider

public PageProvider getPageProvider()
Returns:
the PageProvider applicable to this page-sequence.

getPageSequence

protected PageSequence getPageSequence()
Returns:
the PageSequence being managed by this layout manager

makeNewPage

protected Page makeNewPage(boolean bIsBlank,
                           boolean bIsLast)
Makes a new page
Parameters:
bIsBlank - whether this page is blank or not
bIsLast - whether this page is the last page or not
Returns:
a new page

notifyEndOfLayout

public void notifyEndOfLayout(String id)
Notify the areaTreeHandler that the LayoutManagers containing idrefs have finished creating areas
Parameters:
id - the id for which layout has finished

resolveRetrieveMarker

public RetrieveMarker resolveRetrieveMarker(RetrieveMarker rm)
Bind the RetrieveMarker to the corresponding Marker subtree. If the boundary is page then it will only check the current page. For page-sequence and document it will lookup preceding pages from the area tree and try to find a marker. If we retrieve a marker from a preceding page, then the containing page does not have a qualifying area, and all qualifying areas have ended. Therefore we use last-ending-within-page (Constants.EN_LEWP) as the position.
Parameters:
rm - the RetrieveMarker instance whose properties are to used to find the matching Marker.
Returns:
a bound RetrieveMarker instance, or null if no Marker could be found.

setCurrentPage

protected void setCurrentPage(Page currentPage)
Provides access for setting the current page.
Parameters:
currentPage - the new current Page
