Class SpaceResolver

java.lang.Object
  org.apache.fop.layoutmgr.SpaceResolver

public class SpaceResolver

extends java.lang.Object

This class resolves spaces and conditional borders and paddings by replacing the UnresolvedListElements descendants by the right combination of KnuthElements on an element list.

Nested Class Summary

class	SpaceResolver.SpaceHandlingBreakPosition Position class for break possibilities.
class	SpaceResolver.SpaceHandlingPosition Position class for no-break situations.

SpaceResolver(java.util.List first, BreakElement breakPoss, java.util.List second, boolean isFirst, boolean isLast)
Main constructor.

Method Summary

static void	performConditionalsNotification(java.util.List effectiveList, int startElementIndex, int endElementIndex, int prevBreak) Inspects an effective element list and notifies all layout managers about the state of the spaces and conditional lengths.

Constructor Detail

SpaceResolver

public SpaceResolver(java.util.List first,
                     BreakElement breakPoss,
                     java.util.List second,
                     boolean isFirst,
                     boolean isLast)

Main constructor.

Parameters:

first - Element list before a break (optional)

breakPoss - Break possibility (optional)

second - Element list after a break (or if no break possibility in vicinity)

isFirst - Resolution at the beginning of a (full) element list

isLast - Resolution at the end of a (full) element list

Method Detail

resolveElementList

public static void resolveElementList(java.util.LinkedList elems)

Resolves unresolved elements applying the space resolution rules defined in 4.3.1.

Parameters:

elems - the element list

performConditionalsNotification

public static void performConditionalsNotification(java.util.List effectiveList,
                                                   int startElementIndex,
                                                   int endElementIndex,
                                                   int prevBreak)

Inspects an effective element list and notifies all layout managers about the state of the spaces and conditional lengths.

Parameters:

effectiveList - the effective element list

startElementIndex - index of the first element in the part to be processed

endElementIndex - index of the last element in the part to be processed

prevBreak - index of the the break possibility just before this part (used to identify a break condition, lastBreak <= 0 represents a no-break condition)
