Constructor Detail

KnuthPossPosIter

public KnuthPossPosIter(java.util.List elementList,
                        int startPos,
                        int endPos)
Main constructor

Parameters:
elementList - List of Knuth elements
startPos - starting position, inclusive
endPos - ending position, exclusive

KnuthPossPosIter

public KnuthPossPosIter(java.util.List elementList)
Auxiliary constructor

Parameters:
elementList - List of Knuth elements
Method Detail

checkNext

protected boolean checkNext()

Overrides:
checkNext in class PositionIterator
Returns:
true if not at end of sub-sequence with same child layout manager

next

public Position next()

Specified by:
next in interface java.util.Iterator<Position>
Overrides:
next in class PositionIterator

getKE

public ListElement getKE()
Peek at next, returning as ListElement.

Returns:
peek at next as ListElement

getLM

protected LayoutManager getLM(java.lang.Object nextObj)

Overrides:
getLM in class PositionIterator
Parameters:
nextObj - next object from which to obtain position
Returns:
layout manager

getPos

protected Position getPos(java.lang.Object nextObj)
Default implementation assumes that the passed nextObj is itself a Position, and just returns it. Subclasses for which this is not the case, must provide a suitable override this method.

Overrides:
getPos in class PositionIterator
Parameters:
nextObj - next object from which to obtain position
Returns:
position of next object.
