### curPage

    protected Page curPage

  Current page with page-viewport-area being filled by the PSLM.

### currentPageNum

    protected int currentPageNum

  the current page number

### startPageNum

    protected int startPageNum

  The stating page number

Constructor Detail

### AbstractPageSequenceLayoutManager

    public AbstractPageSequenceLayoutManager(AreaTreeHandler ath,
                                             AbstractPageSequence pseq)

  Constructor

  Parameters:
    `ath` - the area tree handler object
    `pseq` - fo:page-sequence to process

Method Detail

### getLayoutManagerMaker

    public LayoutManagerMaker getLayoutManagerMaker()

  Returns:
    the LayoutManagerMaker object associated to the areaTreeHandler

### getCurrentPage

    public Page getCurrentPage()

  Provides access to the current page.

  Overrides:
    `getCurrentPage` in class `AbstractLayoutManager`
  Returns:
    the current Page
  See Also:
    `getCurrentPage()`

### setCurrentPage

    protected void setCurrentPage(Page currentPage)

  Provides access for setting the current page.

  Parameters:
    `currentPage` - the new current Page

### getCurrentPageNum

    protected int getCurrentPageNum()

  Provides access to the current page number

  Returns:
    the current page number

### initialize

    public void initialize()

  initialize the layout manager. Allows each layout manager to calculate often used values.

  Specified by:
    `initialize` in interface `LayoutManager`
  Overrides:
    `initialize` in class `AbstractLayoutManager`

### getFirstPVWithID

    public PageViewport getFirstPVWithID(java.lang.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(java.lang.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

### addIDToPage

    public void addIDToPage(java.lang.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

### associateLayoutManagerID

    public boolean associateLayoutManagerID(java.lang.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

### notifyEndOfLayout

    public void notifyEndOfLayout(java.lang.String id)

  Notify the areaTreeHandler that the LayoutManagers containing idrefs have finished creating areas

  Parameters:
    `id` - the id for which layout has finished

### addUnresolvedArea

    public void addUnresolvedArea(java.lang.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

### 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.

### createPage

    protected abstract Page createPage(int pageNumber,
                                       boolean isBlank)

  Creates and returns a new page.

  Parameters:
    `pageNumber` - the page number
    `isBlank` - true if it's a blank page
  Returns:
    the newly created page

### makeNewPage

    protected Page makeNewPage(boolean isBlank)

  Makes a new page

  Parameters:
    `isBlank` - whether this page is blank or not
  Returns:
    a new page

### finishPage

    protected void finishPage()

  Finishes a page in preparation for a new page.

### 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.

  Specified by:
    `doForcePageCount` in interface `TopLevelLayoutManager`
  Parameters:
    `nextPageSeqInitialPageNumber` - initial-page-number trait of next page-sequence

### reset

    public void reset()

  Re-initializes this layout manager in order to re-generate its Knuth elements according to a new IPD value.

  Specified by:
    `reset` in interface `LayoutManager`
  Overrides:
    `reset` in class `AbstractLayoutManager`
