Some1 pls explain where the values in the ItemAttribute field defined?

it was call "bit flags". can store mutiple value at once.
example:

A = 0x1
B = 0x2
C = 0x4
D = 0x8

you need to store ABC on variable ItemAttr.
ItemAttr = 1+2+4 (so it was 7)

when you need to try compare value with c++.
you can use & for check bit flags, also use | for set mutiple flags

if(ItemAttr & A)

ItemAttr = A | B | C
