Edge Split Modifier and Sharp edges in the API?

The Blender API has a bit flag for each edge with data such as if the edge is selected and if the edge is marked as a seam. However, I see no mention of if an edge is marked sharp.

Additionally, I see no mention of the Edge Split modifier in the modifiers section of the API. Does the API expose this modifier and this edge property? If so, is it documented anywhere?

Thanks in advance!
