Help! Finding Slabs In Bukkit List Of Materials...

Simply put, I cannot find all of the slabs in the bukkit material list.

My plugin needs to have all of the slabs in an arraylist but I can't find them. Is this an issue with bukkit not having them in their database or are they labeled as something else? Thanks

 

All slabs have the same block ID, so I don't think that all of them will be in the list.

 

Oh they do? Do you know what that ID is by chance?

All ive been able to find on this page is this. Which one should I use?
EDIT: Do I use the dec value?
Double Stone Slab
dec: 43 hex: 2B
Single Stone Slab
dec: 44 hex: 2C
Double Wooden Slab
dec: 125 hex: 7D
Single Wooden Slab
dec: 126 hex: 7E

 

use the decimal value with the getDurability() method

 

Thanks!
