element.getEmbeddedCells([opt])
Return an array of all the embedded cells of an element. If all you need is id
's of all the embedded cells,
use element.get('embeds')
. If opt.deep
is true
, all the deeply embedded
cells will be returned. The order in which the cells are returned depends on the search algorithm used. By
default, Depth-first search (DFS) algorithm is used. If
opt.breadthFirst
is true
, the Breadth-first search algorithm will be used instead.
