Main constructor
Parameters:
position - the Position instance needed by the addAreas stage of the LMs.
length - the length of the element
side - the side to which this element applies
conditional - true if it's a conditional element (conditionality=discard)
isFirst - true if this is a space-before of the first area generated.
isLast - true if this is a space-after of the last area generated.

Returns:
the space as resolved MinOptMax instance

getSide

public RelSide getSide()
Returns:
the side this element was generated for

isFirst

public boolean isFirst()
Returns:
true if this is a space-before of the first area generated.

isLast

public boolean isLast()
Returns:
true if this is a space-after of the last area generated.

notifyLayoutManager

public abstract void notifyLayoutManager(MinOptMax effectiveLength)
Called to notify the affected layout manager about the effective length after resolution. This method is called once before each call to the layout manager's addAreas() method.
