Interface SubSequenceSpecifier

All Known Implementing Classes:
RepeatablePageMasterAlternatives, RepeatablePageMasterReference, SinglePageMasterReference

public interface SubSequenceSpecifier

Classes that implement this interface can be added to a PageSequenceMaster, and are capable of looking up an appropriate SimplePageMaster.


Method Summary

 SimplePageMaster getLastPageMaster(boolean isOddPage, boolean isFirstPage, boolean isBlankPage, BlockLevelEventProducer blockLevelEventProducer)
           
 SimplePageMaster getNextPageMaster(boolean isOddPage, boolean isFirstPage, boolean isLastPage, boolean isBlankPage)
          Returns the name of the next page master.
 boolean goToPrevious()
          Used to set the "cursor position" to the previous item.

 boolean hasPagePositionOnly()
           
 boolean isInfinite()
          Test that this is a finite sequence
 boolean isReusable()
          Test if this can be reused when it is the last sub-sequence specifer, and has been exhausted
 void reset()
          Called before a new page sequence is rendered so subsequences can reset any state they keep during the formatting process.
 void resolveReferences(LayoutMasterSet layoutMasterSet)

Method Detail

getNextPageMaster

SimplePageMaster getNextPageMaster(boolean isOddPage,
                                   boolean isFirstPage,
                                   boolean isLastPage,
                                   boolean isBlankPage)
                                   throws PageProductionException
Returns the name of the next page master.

Parameters:
isOddPage - True if the next page number is odd
isFirstPage - True if the next page is the first
isLastPage - True if the next page is the last
isBlankPage - True if the next page is blank
Returns:
the page master name
Throws:
PageProductionException - if there's a problem determining the next page master

getLastPageMaster

SimplePageMaster getLastPageMaster(boolean isOddPage,
                                   boolean isFirstPage,
                                   boolean isBlankPage,
                                   BlockLevelEventProducer blockLevelEventProducer)
                                   throws PageProductionException
Throws:
PageProductionException

reset

void reset()
Called before a new page sequence is rendered so subsequences can reset any state they keep during the formatting process.


goToPrevious

boolean goToPrevious()
Used to set the "cursor position" to the previous item.

Returns:
true if there is a previous item, false if the current one was the first one.

hasPagePositionLast

boolean hasPagePositionLast()
Returns:
true if the subsequence has a page master for page-position "last"

hasPagePositionOnly

boolean hasPagePositionOnly()
Returns:
true if the subsequence has a page master for page-position "only"

resolveReferences

void resolveReferences(LayoutMasterSet layoutMasterSet)
                       throws ValidationException
called by the parent LayoutMasterSet to resolve object references from simple page master reference names

Parameters:
layoutMasterSet - the layout-master-set
Throws:
ValidationException - when a named reference cannot be resolved

canProcess

boolean canProcess(java.lang.String flowName)
Parameters:
flowName - name of the main flow
Returns:
true iff page sequence is a finite sequence or can process the entire main flow

isInfinite

boolean isInfinite()
Test that this is a finite sequence

Returns:
true iff this is a finite sequence

isReusable

boolean isReusable()
Test if this can be reused when it is the last sub-sequence specifer, and has been exhausted

Returns:
true if and only if it can be reused
