Constant Field Values

EXCEPTION

static final int EXCEPTION

Denotes a control flow graph edge corresponding to an exception handler. More precisely any Edge whose info is strictly positive corresponds to an exception handler. The actual value of info is the index, in the ClassWriter type table, of the exception that is catched.

Constant Field Values

info

int info

Information about this control flow graph edge. If ClassWriter.COMPUTE_MAXS is used this field is the (relative) stack size in the basic block from which this edge originates. This size is equal to the stack size at the "jump" instruction to which this edge corresponds, relatively to the stack size at the beginning of the originating basic block. If ClassWriter.COMPUTE_FRAMES is used, this field is the kind of this control flow graph edge (i.e. NORMAL or EXCEPTION).

successor

Label successor

The successor block of the basic block from which this edge originates.

next

Edge next

The next edge in the list of successors of the originating basic block. See successors.
