Constructor Details

KnuthPossPosIter

public KnuthPossPosIter(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(List elementList)

Auxiliary constructor

Parameters:

elementList - List of Knuth elements

Method Details

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 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(Object nextObj)

Overrides:

getLM in class PositionIterator

Parameters:

nextObj - next object from which to obtain position

Returns:

layout manager

getPos

protected Position getPos(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.
