                                 Operand Unknown1,
                                 Operand Unknown2,
                                 IntConstantOperand Low,
                                 IntConstantOperand High,
                                 BranchOperand Default,
                                 BranchProfileOperand DefaultBranchProfile,
                                 int numVarOps)

Create an instruction of the TableSwitch instruction format.

Parameters:: o - the instruction's operator; Value - the instruction's Value operand; Unknown1 - the instruction's Unknown1 operand; Unknown2 - the instruction's Unknown2 operand; Low - the instruction's Low operand; High - the instruction's High operand; Default - the instruction's Default operand; DefaultBranchProfile - the instruction's DefaultBranchProfile operand; numVarOps - the number of variable length operands that will be stored in the insruction.
Returns:: the newly created TableSwitch instruction

mutate

public static Instruction mutate(Instruction i,
                                 Operator o,
                                 Operand Value,
                                 Operand Unknown1,
                                 Operand Unknown2,
                                 IntConstantOperand Low,
                                 IntConstantOperand High,
                                 BranchOperand Default,
                                 BranchProfileOperand DefaultBranchProfile,
                                 int numVarOps)

Mutate the argument instruction into an instruction of the TableSwitch instruction format having the specified operator and operands.

Parameters:: i - the instruction to mutate; o - the instruction's operator; Value - the instruction's Value operand; Unknown1 - the instruction's Unknown1 operand; Unknown2 - the instruction's Unknown2 operand; Low - the instruction's Low operand; High - the instruction's High operand; Default - the instruction's Default operand; DefaultBranchProfile - the instruction's DefaultBranchProfile operand; numVarOps - the number of variable length operands that will be stored in the insruction.
Returns:: the mutated instruction
