Block type & data casted to Directional or BlockFace

I need to rotate and flip some structures and I got to the point where I need to "rotate" individual blocks by changing their data, basically I need to input block type and data to something and get the Directional or BlockFace class of it.

I tried a code I found in a search result modified to my needs:

Code:

MaterialData mat = Material.getMaterial(stored.type).getNewData(stored.data);
Directional matDir = ((Directional)mat);

But it can't cast from MaterialData to Directional :/
Also, I don't have access to the Block class, I just have the type and data values.
Anyone got an ideea how to solve this ?

An alternative would be to store the blockface when I copy the blocks, but that would mean more memory usage that's really unrequired since I have all I need in the "data" field.

 

Try this:

Code:

MaterialData mat = Material.getMaterial(stored.type).getNewData(stored.data);
if (mat instanceof Directional) { //has a direction, i.e. is rotatable
    Directional matDir = ((Directional)mat);
} else //not rotatable

 

Hmm yeah I forgot to check if each individual block types can be rotated =) damn lack of sleep.
Well, that works, thanks :}

Now for the next thing... anyone got an ideea how to quickly "rotate" through the block faces ? I mean *all* block faces: N, NE, NNE, S, SW, etc.
For flip I think .getOppositeFace() works just fine for signs too... but I'll test that out.

EDIT: dammit, it doesn't pass the condition on all directional blocks, stairs for example.
EDIT: it seems smooth and nether stairs don't have directional interface... :/
