Field Detail

areaTreeHandler

protected AreaTreeHandler areaTreeHandler

AreaTreeHandler which activates the PSLM and controls the rendering of its pages.

idTracker

protected IDTracker idTracker

ID tracker supplied by the AreaTreeHandler

pageSeq

protected AbstractPageSequence pageSeq

page sequence formatting object being processed by this class

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

getLastPageNumber

protected int getLastPageNumber()
