Class JumpInsnNode
public class JumpInsnNode
A node that represents a jump instruction. A jump instruction is an
instruction that may jump to another instruction.

label
public LabelNode label
The operand of this instruction. This operand is a label that designates
the instruction to which this instruction may jump.
JumpInsnNode
public JumpInsnNode(int opcode,
LabelNode label)
opcode
- the opcode of the type instruction to be constructed. This
opcode must be IFEQ, IFNE, IFLT, IFGE, IFGT, IFLE, IF_ICMPEQ,
IF_ICMPNE, IF_ICMPLT, IF_ICMPGE, IF_ICMPGT, IF_ICMPLE, IF_ACMPEQ,
IF_ACMPNE, GOTO, JSR, IFNULL or IFNONNULL.label
- the operand of the instruction to be constructed. This
operand is a label that designates the instruction to which the
jump instruction may jump.
clone
public AbstractInsnNode clone(Map labels)
Returns a copy of this instruction.
- clone in interface AbstractInsnNode
labels
- a map from LabelNodes to cloned LabelNodes.
- a copy of this instruction. The returned instruction does not
belong to any
InsnList
.
getType
public int getType()
Returns the type of this instruction.
- getType in interface AbstractInsnNode
- the type of this instruction, i.e. one the constants defined in
this class.
setOpcode
public void setOpcode(int opcode)
Sets the opcode of this instruction.
opcode
- the new instruction opcode. This opcode must be IFEQ, IFNE,
IFLT, IFGE, IFGT, IFLE, IF_ICMPEQ, IF_ICMPNE, IF_ICMPLT,
IF_ICMPGE, IF_ICMPGT, IF_ICMPLE, IF_ACMPEQ, IF_ACMPNE, GOTO, JSR,
IFNULL or IFNONNULL.
