FALL_THROUGH

static final int FALL_THROUGH

Denotes an instruction that ends a basic block and may let control flow fall through to its lexical successor. In practice this means it is a conditional branch.

Constant Field Values

BRANCH

static final int BRANCH

Denotes an instruction that has a 2 or 4 byte operand that is an offset to another instruction in the same method. This does not include the Bytecodes.TABLESWITCH or Bytecodes.LOOKUPSWITCH instructions.
