public IRenderer getNextRenderer()
BlockRenderer.layout(LayoutContext)
is called more than once.
If a renderer overflows to the next area, iText uses this method to create a renderer for the overflow part. So if one wants to extend CellRenderer
, one should override this method: otherwise the default method will be used and thus the default rather than the custom renderer will be created.
