Chapter 12 Variables
107
?The definite assignment state of v at the beginning of try-block is the
same as the definite
assignment state of v at the beginning of stmt.
?The definite assignment state of v at the beginning of finally-block is
the same as the definite
assignment state of v at the beginning of stmt.
?The definite assignment state of v at the end-point of stmt is definitely
assigned if (and only if)
either:
o v is definitely assigned at the end-point of try-block
o v is definitely assigned at the end-point of finally-block
If a control flow transfer (such as a goto statement) is made that begins
within try-block, and ends outside
of try-block, then v is also considered definitely assigned on that control
flow transfer if v is definitely
assigned at the end-point of finally-block. (This is not an only if.if v is
definitely assigned for another
reason on this control flow transfer, then it is still considered
definitely assigned.)
