    - #### 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:
