             int arg,
             ClassWriter cw,
             Item item)

Sets this CurrentFrame to the input stack map frame of the next "current" instruction, i.e. the instruction just after the given one. It is assumed that the value of this object when this method is called is the stack map frame status just before the given instruction is executed.

Overrides:

Parameters:

opcode - the opcode of the instruction.

arg - the operand of the instruction, if any.

cw - the class writer to which this label belongs.

item - the operand of the instructions, if any.
