Method Detail

getHeight

public long getHeight()

add

public long add(InlineSequenceElement sequenceElement)

Adding unaligned elements increases the total height and either shifts the stored baselines upward or downwards. If a bottom aligned element is greater than the already seen content, extending the total height will require a shift of the computed last baseline by the added height. The returned position will only be valid, if the total lineheight will not change while adding nodes.

Parameters:

height -

shiftDown -

Returns:

the position of the top edge of the node.
