breakLabel

Label breakLabel()
Returns the label locating where control is passed back to the parent block. A branch to this label "break"'s out of the current block.

If the last instruction in this block does not lead to the break label, Class-File API may append instructions to target the "break" label to the built block.

Returns:
the label locating where control is passed back to the parent block
